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 L2126, one of those codes.
Code name (*): L2126 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Senftleben, PSieve, Srsieve, PrimeGrid, LLR Number of primes: total 43 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 47.7131, on current list 45.4788 (normalized score 3) Entrance Rank (*): mean 1794.00 (minimum 379, maximum 3209)
