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 c8, one of those codes.
Code name (*): c8 Persons (*): 2 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Water, Broadhurst, Primo Number of primes: total 314 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess') Score for Primes (*): total 36.6091, on current list 35.9486 Entrance Rank (*): mean 63606.55 (minimum 28211, maximum 86383)
