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 L3213, one of those codes.
Code name (*): L3213 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): OBrien1, PSieve, Srsieve, PrimeGrid, LLR Number of primes: total 6 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 45.4746, on current list 44.8588 (normalized score 1) Entrance Rank (*): mean 391.00 (minimum 391, maximum 391)
