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 L1958, one of those codes.
Code name (*): L1958 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): DUrso, Srsieve, NewPGen, OpenPFGW, LLR Number of primes: total 38 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 46.5141, on current list 44.6533 (normalized score 1) Entrance Rank (*): mean 3702.00 (minimum 3702, maximum 3702)
