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 p281, one of those codes.
Code name (*): p281 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Domanov1, Srsieve, NPLB, Prime95, OpenPFGW Number of primes: total 3 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 45.3664, on current list 45.2163 (normalized score 3) Entrance Rank (*): mean 114.00 (minimum 92, maximum 136)
