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 c47, one of those codes.
Code name (*): c47 Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Chandler, Primo Number of primes: total 15 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 36.3689, on current list 36.3644 Entrance Rank (*): mean 55322.36 (minimum 45339, maximum 67888)
Below is additional information about this entry.
