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 L4747, one of those codes.
Code name (*): L4747 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Brech, GFNSvCUDA, GeneFer, AthGFNSieve, PrimeGrid, LLR Number of primes: total 66 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 48.9412, on current list 48.9412 (normalized score 93) Entrance Rank (*): mean 2356.35 (minimum 356, maximum 2963)
