# Proof-code: p422

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 p422, one of those codes.

Code name(*):p422 Persons(*):1 (counting humans only) Projects(*):0 (counting projects only) Display (HTML):Kaiser1, PolySieve, OpenPFGW Number of primes:total 6 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 34.4104, on current list 33.3118 Entrance Rank(*):mean 77098.50 (minimum 77095, maximum 77102)
