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 C, one of those codes.
Code name (*): C Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Caldwell, Cruncher Number of primes: total 120 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 36.5408, on current list 34.0441 Entrance Rank (*): mean 41.25 (minimum 28, maximum 53)
