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 L5516, one of those codes.
Code name (*): L5516 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Piesker, PSieve, Srsieve, NPLB, LLR Number of primes: total 67 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 49.2027, on current list 49.1196 (normalized score 87) Entrance Rank (*): mean 3419.02 (minimum 3124, maximum 4317)
