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 p271, one of those codes.
Code name (*): p271 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Dettweiler, Srsieve, CRUS, OpenPFGW Number of primes: total 8 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 45.7623, on current list 45.3027 (normalized score 2) Entrance Rank (*): mean 228.00 (minimum 228, maximum 228)
