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 p392, one of those codes.
Code name (*): p392 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Batalov, Cksieve, OpenPFGW Number of primes: total 3 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 45.1460, on current list 44.2929 (normalized score 1) Entrance Rank (*): mean 1771.00 (minimum 1771, maximum 1771)
