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 p341, one of those codes.
Code name (*): p341 Persons (*): 1 (counting humans only) Projects (*): 2 (counting projects only) Display (HTML): Schmidt2, Srsieve, PrimeGrid, SierpinskiRiesel, OpenPFGW Number of primes: total 2 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 45.3032, on current list 45.3032 (normalized score 2) Entrance Rank (*): mean 204.50 (minimum 191, maximum 218)
