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 L321, one of those codes.
Code name (*): L321 (See the descriptive data below.) Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Broadhurst, NewPGen, OpenPFGW, LLR Number of primes: total 5 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 45.7530, on current list 45.6498 (normalized score 3) Entrance Rank (*): mean 42.50 (minimum 39, maximum 46)
