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 L381, one of those codes.
Code name (*): L381 Persons (*): 3 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Mate, Siemelink, Rodenkirch, MultiSieve, LLR Number of primes: total 1 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 44.1253, on current list 44.1253 (normalized score 1) Entrance Rank (*): mean 68.00 (minimum 68, maximum 68)
