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 L4001, one of those codes.
Code name (*): L4001 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Willig, Srsieve, CRUS, LLR Number of primes: total 174 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 50.5095, on current list 50.4382 (normalized score 499) Entrance Rank (*): mean 1415.29 (minimum 87, maximum 2686)
