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 c71, one of those codes.
Code name (*): c71 Persons (*): 3 (counting humans only) Projects (*): 1 (counting projects only) Display (HTML): Metcalfe, Ritschel, Andersen, TOPS, Primo Number of primes: total 1 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 33.4517, on current list 33.4517 Entrance Rank (*): mean 62174.00 (minimum 62174, maximum 62174)
