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 L3313, one of those codes.
Code name (*): L3313 Persons (*): 1 (counting humans only) Projects (*): 2 (counting projects only) Display (HTML): Yost, Srsieve, PrimeGrid, SierpinskiRiesel, LLR Number of primes: total 3 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 46.2082, on current list 46.2082 (normalized score 6) Entrance Rank (*): mean 171.33 (minimum 168, maximum 176)
