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 G12, one of those codes.
Code name (*): G12 Persons (*): 1 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Strindmo, GIMPS, Prime95 Number of primes: total 1 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 54.4507, on current list 54.4507 (normalized score 23977) Entrance Rank (*): mean 2.00 (minimum 2, maximum 2)
Below is additional information about this entry.
