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 p300, one of those codes.
Code name (*): p300 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Gramolin, NewPGen, OpenPFGW Number of primes: total 3 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 45.9954, on current list 45.9718 (normalized score 5) Entrance Rank (*): mean 137.00 (minimum 126, maximum 148)
