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 L4853, one of those codes.
Code name (*): L4853 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Jackson1, GFNSvCUDA, GeneFer, AthGFNSieve, PrimeGrid, LLR Number of primes: total 21 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 47.6260, on current list 47.6260 (normalized score 31) Entrance Rank (*): mean 2410.81 (minimum 2211, maximum 2683)
