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 L4609, one of those codes.
Code name (*): L4609 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Elgetz, PSieve, Srsieve, PrimeGrid, LLR Number of primes: total 2 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 46.7885, on current list 46.6969 (normalized score 8) Entrance Rank (*): mean 204.00 (minimum 204, maximum 204)
