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 p260, one of those codes.
Code name (*): p260 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Harvey, Gcwsieve, MultiSieve, GenWoodall, OpenPFGW Number of primes: total 21 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 45.7862, on current list 44.2372 (normalized score 1) Entrance Rank (*): mean 2359.00 (minimum 2359, maximum 2359)
