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 L2257, one of those codes.
Code name (*): L2257 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Dettweiler, PSieve, Srsieve, NPLB, LLR Number of primes: total 130 Unverified Primes: 1 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 49.3769, on current list 48.9582 (normalized score 70) Entrance Rank (*): mean 3657.75 (minimum 2735, maximum 3890)
