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 p338, one of those codes.
Code name (*): p338 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Tomecko, GeneferCUDA, AthGFNSieve, PrimeGrid, OpenPFGW Number of primes: total 1 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 47.8758, on current list 47.8758 (normalized score 31) Entrance Rank (*): mean 24.00 (minimum 24, maximum 24)
