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 g407, one of those codes.
Code name (*): g407 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): HermleGC, MultiSieve, PRP, Proth.exe Number of primes: total 8 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 46.5789, on current list 46.4691 (normalized score 8) Entrance Rank (*): mean 123.00 (minimum 103, maximum 143)
