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 c77, one of those codes.
Code name (*): c77 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Batalov, Primo Number of primes: total 46 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 37.5505, on current list 37.5503 Entrance Rank (*): mean 69047.47 (minimum 64602, maximum 82362)
