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 WD, one of those codes.
Code name (*): WD Persons (*): 2 (counting humans only) Projects (*): 0 (counting projects only) Display (HTML): Williams, Dubner, Cruncher Number of primes: total 1 Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes (*): total 25.3646, on current list 25.3646 Entrance Rank (*): mean 565.00 (minimum 565, maximum 565)
