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 p419, one of those codes.
Code name (*): p419 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Bird1, LLR2, PrivGfnServer, OpenPFGW Number of primes: total 1 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 46.6330, on current list 46.6330 (normalized score 9) Entrance Rank (*): mean 1014.00 (minimum 1014, maximum 1014)
