Proof-code: A68

Previous Next Random

Samuel Yates began, and this site continues, a database of the largest known primes. Primes in that database are assigned a proof-code to show who should be credited with the discovery as well as what programs and projects they used. (Discoverers have one prover-entry, but may have many proof-codes because they use a variety of programs...)

This page provides data on A68, one of those codes.

Code name (*): A68

Persons (*): 1 (counting humans only)

Projects (*): 1 (counting projects only)

Display (HTML): Schroeder3, Srsieve, CRUS, PRST

Number of primes: total 20

Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess'

Score for Primes (*): total 49.7614, on current list 49.5753 (normalized score 28)

Entrance Rank (*): mean 2102.83 (minimum 759, maximum 4820)

I am a member of this code and I would like to:

Below is additional information about this entry.

Display (text): Schroeder3, Srsieve, CRUS, PRST

Display (short): Schroeder3

Database id: 10552 (do not use this database id, it is subject to change)

Proof program: PRST The primes from this code accounts for 4.096% of the (active) primes and 0.299% of the (active) score for this program.
