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 p350, one of those codes.
Code name (*): p350 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Koen, Gcwsieve, GenWoodall, OpenPFGW Number of primes: total 1 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 45.8589, on current list 45.8589 (normalized score 4) Entrance Rank (*): mean 78.00 (minimum 78, maximum 78)
