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 82 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 48.3044, on current list 46.5617 (normalized score 10) Entrance Rank (*): mean 3029.20 (minimum 2902, maximum 3158)
