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 p408, one of those codes.
Code name (*): p408 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Batalov, PolySieve, OpenPFGW Number of primes: total 2 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 33.5433, on current list 33.5433 Entrance Rank (*): mean 74770.50 (minimum 74336, maximum 75205)
