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 L4245, one of those codes.
Code name (*): L4245 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Greer, GFNSvCUDA, GeneFer, AthGFNSieve, PrimeGrid, LLR Number of primes: total 42 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 49.6472, on current list 49.6215 (normalized score 217) Entrance Rank (*): mean 1539.36 (minimum 87, maximum 2756)
