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 g259, one of those codes.
Code name (*): g259 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Papp, Proth.exe Number of primes: total 43 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 41.2448, on current list 38.1767 Entrance Rank (*): mean 819.50 (minimum 819, maximum 820)
