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 L5123, one of those codes.
Code name (*): L5123 Persons (*): 2 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Propper, Batalov, EMsieve, LLR Number of primes: total 1 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 51.3176, on current list 51.3176 (normalized score 1199) Entrance Rank (*): mean 20.00 (minimum 20, maximum 20)
