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 L5261, one of those codes.
Code name (*): L5261 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Kim5, LLR2, PSieve, Srsieve, PrimeGrid, LLR Number of primes: total 20 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 49.6760, on current list 49.6760 (normalized score 148) Entrance Rank (*): mean 757.15 (minimum 700, maximum 1080)
