Proof-code: A67

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 A67, one of those codes.

Code name (*): A67

Persons (*): 1 (counting humans only)

Projects (*): 0 (counting projects only)

Display (HTML): Gahan, Gcwsieve, PRST

Number of primes: total 3

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

Score for Primes (*): total 47.7079, on current list 47.7079 (normalized score 8)

Entrance Rank (*): mean 3120.33 (minimum 1017, maximum 4496)
