# Proof-code: p421

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 p421, one of those codes.

Code name(*):p421 Persons(*):1 (counting humans only) Projects(*):1 (counting projects only) Display (HTML):Gahan, LLR2, PrivGfnServer, OpenPFGW Number of primes:total 1 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 46.6330, on current list 46.6330 (normalized score 9) Entrance Rank(*):mean 1089.00 (minimum 1089, maximum 1089)
