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 g277, one of those codes.
Code name (*): g277 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Eaton, NewPGen, PRP, Proth.exe Number of primes: total 7 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 43.6043, on current list 42.8233 Entrance Rank (*): mean 82.00 (minimum 82, maximum 82)
Below is additional information about this entry.
