How to read these numbers
Classical average ≈ 46,052 candidates

For random integers of about 20,000 digits, the classical baseline predicts one prime on average every approximately 46,052 candidates.

Candidates tested so far 550 candidates

This is the number of candidates examined so far in this Challenge.

Classical success probability at this point 1.19%

Under simple random generation, this is the probability of finding at least one prime among the first 550 random integers of approximately 20,000 digits.

Classical success probability within the full limit 4.25%

Before the Challenge began, this was the classical probability of finding at least one prime within the complete limit of 2,000 candidates.

What this Challenge means
The Challenge is still in progress. The current expectations are therefore probabilistic, not a final result. Under the classical random-integer baseline, the probability of at least one prime by the current point is 1.19%, while the probability within the full planned limit is 4.25%. An observed advantage can be calculated only after an officially verified hit.
Formulas and complete calculations
1. Probability for one random integer p ≈ 1 / (20,000 × ln(10)) = 0.0000217147 The prime number theorem gives an approximate probability of 1 / ln(N). A number with 20,000 decimal digits has ln(N) approximately equal to 20,000 × ln(10).
2. Classical average number of candidates 1 / p ≈ 46,052 This is an average, not a guaranteed position. A prime may appear earlier or later.
3. Probability of at least one prime within the tested candidates 1 − (1 − p)^550 = 1.19% This calculation refers specifically to random integers of approximately 20,000 digits.
4. Probability of at least one prime within the full planned limit 1 − (1 − p)^2000 = 4.25% This is the success probability assigned by the classical random-integer baseline before the complete Challenge range is tested.
Important: these calculations use the simple classical baseline for unrestricted random integers of the same approximate digit length. They provide a transparent reference point for each Challenge. They do not replace complete density experiments, and a single first-hit result cannot by itself establish the long-run enrichment of the full sequence.

Verify the results yourself

Every official result can be reproduced independently using the public MAX Prime client and the mathematical values published on this page.

Reproduce the same candidate on your computer

Open the public MAX Prime client from GitHub and use Local Mode. Copy the published n_raw value as the local starting value, keep the published CRT modulus M and remainder R, select 1 iteration and test N.

The client must generate a probable prime with the same number of digits and exactly the same SHA-256 shown on this page.

If the digit count and SHA-256 match, your computer has independently reconstructed the same MAX Prime candidate using the public source code and the published mathematical data.

Classical average ≈ 39,291 candidates

For random integers of about 17,064 digits, the classical baseline predicts one prime on average every approximately 39,291 candidates.

Observed result 361 candidates

A verified probable prime was found after this number of tested candidates.

Observed advantage 108.84×

The result arrived after 361 candidates instead of the classical average of about 39,291. In practice, this Challenge required about 108.84 times fewer candidate-testing operations than the classical average for random integers of the same size.

Classical success probability at this point 0.91%

Under simple random generation, this is the probability of finding at least one prime among the first 361 random integers of approximately 17,064 digits.

Classical success probability within the full limit 4.96%

Before the Challenge began, this was the classical probability of finding at least one prime within the complete limit of 2,000 candidates.

What this Challenge means
A verified probable prime of approximately 17,064 digits was found after 361 candidates. The classical average is about 39,291 candidates, so the observed result shows a 108.84× advantage in the number of candidate-testing operations. At the point of discovery, the classical cumulative probability of already having found at least one prime was 0.91%, compared with 4.96% within the full planned limit.
Formulas and complete calculations
1. Probability for one random integer p ≈ 1 / (17,064 × ln(10)) = 0.0000254509 The prime number theorem gives an approximate probability of 1 / ln(N). A number with 17,064 decimal digits has ln(N) approximately equal to 17,064 × ln(10).
2. Classical average number of candidates 1 / p ≈ 39,291 This is an average, not a guaranteed position. A prime may appear earlier or later.
3. Probability of at least one prime within the tested candidates 1 − (1 − p)^361 = 0.91% This calculation refers specifically to random integers of approximately 17,064 digits.
4. Probability of at least one prime within the full planned limit 1 − (1 − p)^2000 = 4.96% This is the success probability assigned by the classical random-integer baseline before the complete Challenge range is tested.
5. Observed advantage in candidate-testing operations 39,291 / 361 = 108.840200× This compares the classical average number of candidates with the number actually required to reach the first verified hit. It is not a probability and it is not, by itself, a measurement of long-run prime density.
Important: these calculations use the simple classical baseline for unrestricted random integers of the same approximate digit length. They provide a transparent reference point for each Challenge. They do not replace complete density experiments, and a single first-hit result cannot by itself establish the long-run enrichment of the full sequence.

In this one-iteration local check, the local iteration index will be zero, but the generated n_raw, n_effective, candidate, digit count and SHA-256 must match the official values published here.

If the digit count and SHA-256 match, your computer has independently reconstructed the same MAX Prime candidate using the public source code and the published mathematical data.

How to read these numbers
Continuation accounting 2,083 cumulative candidates

This block has tested 83 of 2,000 new candidates, after 2,000 candidates were already completed in the previous contiguous range. Mathematical probabilities and any future observed advantage use the cumulative total.

Classical average ≈ 31,076 candidates

For random integers of about 13,496 digits, the classical baseline predicts one prime on average every approximately 31,076 candidates.

Observed result 2,083 candidates

A verified probable prime was found after this number of tested candidates.

Observed advantage 14.92×

The result arrived after 2,083 candidates instead of the classical average of about 31,076. In practice, this Challenge required about 14.92 times fewer candidate-testing operations than the classical average for random integers of the same size.

Classical success probability at this point 6.48%

Under simple random generation, this is the probability of finding at least one prime among the first 2,083 random integers of approximately 13,496 digits.

Classical success probability within the full limit 12.08%

Before the Challenge began, this was the classical probability of finding at least one prime within the complete limit of 4,000 candidates.

What this Challenge means
A verified probable prime of approximately 13,496 digits was found after 2,083 candidates. The classical average is about 31,076 candidates, so the observed result shows a 14.92× advantage in the number of candidate-testing operations. At the point of discovery, the classical cumulative probability of already having found at least one prime was 6.48%, compared with 12.08% within the full planned limit.
Formulas and complete calculations
1. Probability for one random integer p ≈ 1 / (13,496 × ln(10)) = 0.0000321795 The prime number theorem gives an approximate probability of 1 / ln(N). A number with 13,496 decimal digits has ln(N) approximately equal to 13,496 × ln(10).
2. Classical average number of candidates 1 / p ≈ 31,076 This is an average, not a guaranteed position. A prime may appear earlier or later.
3. Probability of at least one prime within the tested candidates 1 − (1 − p)^2083 = 6.48% This calculation refers specifically to random integers of approximately 13,496 digits.
4. Probability of at least one prime within the full planned limit 1 − (1 − p)^4000 = 12.08% This is the success probability assigned by the classical random-integer baseline before the complete Challenge range is tested.
5. Observed advantage in candidate-testing operations 31,076 / 2,083 = 14.918717× This compares the classical average number of candidates with the number actually required to reach the first verified hit. It is not a probability and it is not, by itself, a measurement of long-run prime density.
Important: these calculations use the simple classical baseline for unrestricted random integers of the same approximate digit length. They provide a transparent reference point for each Challenge. They do not replace complete density experiments, and a single first-hit result cannot by itself establish the long-run enrichment of the full sequence.

Verify this result with the public MAX Prime client

You can reproduce this result independently using the public Rust client available on GitHub. Open Local Mode, select the advanced/custom experiment and run exactly one iteration.

To avoid repeating all previous iterations, use the published n_raw value below as the local starting value. Then copy the published CRT modulus M and remainder R, keep the filter enabled, select N and set the number of iterations to 1.

In this one-iteration local check, the local iteration index will be zero, but the generated n_raw, n_effective, candidate, digit count and SHA-256 must match the official values published here.

If the digit count and SHA-256 match, your computer has independently reconstructed the same MAX Prime candidate using the public source code and the published mathematical data.

How to read these numbers
Classical average ≈ 23,687 candidates

For random integers of about 10,287 digits, the classical baseline predicts one prime on average every approximately 23,687 candidates.

Observed result 1,005 candidates

A verified probable prime was found after this number of tested candidates.

Observed advantage 23.57×

The result arrived after 1,005 candidates instead of the classical average of about 23,687. In practice, this Challenge required about 23.57 times fewer candidate-testing operations than the classical average for random integers of the same size.

Classical success probability at this point 4.15%

Under simple random generation, this is the probability of finding at least one prime among the first 1,005 random integers of approximately 10,287 digits.

Classical success probability within the full limit 8.10%

Before the Challenge began, this was the classical probability of finding at least one prime within the complete limit of 2,000 candidates.

What this Challenge means
A verified probable prime of approximately 10,287 digits was found after 1,005 candidates. The classical average is about 23,687 candidates, so the observed result shows a 23.57× advantage in the number of candidate-testing operations. At the point of discovery, the classical cumulative probability of already having found at least one prime was 4.15%, compared with 8.10% within the full planned limit.
Formulas and complete calculations
1. Probability for one random integer p ≈ 1 / (10,287 × ln(10)) = 0.0000422178 The prime number theorem gives an approximate probability of 1 / ln(N). A number with 10,287 decimal digits has ln(N) approximately equal to 10,287 × ln(10).
2. Classical average number of candidates 1 / p ≈ 23,687 This is an average, not a guaranteed position. A prime may appear earlier or later.
3. Probability of at least one prime within the tested candidates 1 − (1 − p)^1005 = 4.15% This calculation refers specifically to random integers of approximately 10,287 digits.
4. Probability of at least one prime within the full planned limit 1 − (1 − p)^2000 = 8.10% This is the success probability assigned by the classical random-integer baseline before the complete Challenge range is tested.
5. Observed advantage in candidate-testing operations 23,687 / 1,005 = 23.568849× This compares the classical average number of candidates with the number actually required to reach the first verified hit. It is not a probability and it is not, by itself, a measurement of long-run prime density.
Important: these calculations use the simple classical baseline for unrestricted random integers of the same approximate digit length. They provide a transparent reference point for each Challenge. They do not replace complete density experiments, and a single first-hit result cannot by itself establish the long-run enrichment of the full sequence.

Classical average ≈ 11,817 candidates

For random integers of about 5,132 digits, the classical baseline predicts one prime on average every approximately 11,817 candidates.

Observed result 317 candidates

A verified probable prime was found after this number of tested candidates.

Observed advantage 37.28×

The result arrived after 317 candidates instead of the classical average of about 11,817. In practice, this Challenge required about 37.28 times fewer candidate-testing operations than the classical average for random integers of the same size.

Classical success probability at this point 2.65%

Under simple random generation, this is the probability of finding at least one prime among the first 317 random integers of approximately 5,132 digits.

Classical success probability within the full limit 15.57%

Before the Challenge began, this was the classical probability of finding at least one prime within the complete limit of 2,000 candidates.

What this Challenge means
A verified probable prime of approximately 5,132 digits was found after 317 candidates. The classical average is about 11,817 candidates, so the observed result shows a 37.28× advantage in the number of candidate-testing operations. At the point of discovery, the classical cumulative probability of already having found at least one prime was 2.65%, compared with 15.57% within the full planned limit.
Formulas and complete calculations
1. Probability for one random integer p ≈ 1 / (5,132 × ln(10)) = 0.0000846248 The prime number theorem gives an approximate probability of 1 / ln(N). A number with 5,132 decimal digits has ln(N) approximately equal to 5,132 × ln(10).
2. Classical average number of candidates 1 / p ≈ 11,817 This is an average, not a guaranteed position. A prime may appear earlier or later.
3. Probability of at least one prime within the tested candidates 1 − (1 − p)^317 = 2.65% This calculation refers specifically to random integers of approximately 5,132 digits.
4. Probability of at least one prime within the full planned limit 1 − (1 − p)^2000 = 15.57% This is the success probability assigned by the classical random-integer baseline before the complete Challenge range is tested.
5. Observed advantage in candidate-testing operations 11,817 / 317 = 37.277182× This compares the classical average number of candidates with the number actually required to reach the first verified hit. It is not a probability and it is not, by itself, a measurement of long-run prime density.
Important: these calculations use the simple classical baseline for unrestricted random integers of the same approximate digit length. They provide a transparent reference point for each Challenge. They do not replace complete density experiments, and a single first-hit result cannot by itself establish the long-run enrichment of the full sequence.

You can reproduce this result independently using the public Rust client available on GitHub. Open Local Mode, select the advanced/custom experiment and run exactly one iteration.

To avoid repeating all previous iterations, use the published n_raw value below as the local starting value. Then copy the published CRT modulus M and remainder R, keep the filter enabled, select N and set the number of iterations to 1.

Iterations 1
Test N
CRT filter ON — use the published M and R

In this one-iteration local check, the local iteration index will be zero, but the generated n_raw, n_effective, candidate, digit count and SHA-256 must match the official values published here.

If the digit count and SHA-256 match, your computer has independently reconstructed the same MAX Prime candidate using the public source code and the published mathematical data.

Expected digits: 5132
Expected SHA-256:
