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 L4977, one of those codes.
Code name (*): L4977 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Miller8, GFNSvCUDA, GeneFer, AthGFNSieve, PrimeGrid, LLR Number of primes: total 9 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 47.7685, on current list 47.7685 (normalized score 28) Entrance Rank (*): mean 2255.56 (minimum 384, maximum 2932)
