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 D, one of those codes.
Code name (*): D Persons (*): 1 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Dubner, Cruncher Number of primes: total 4423 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 43.9426, on current list 32.3578 Entrance Rank (*): mean 432.67 (minimum 7, maximum 1655)
