# Proof-code: p258

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 p258, one of those codes.

Code name(*):p258 Persons(*):1 (counting humans only) Projects(*):1 (counting projects only) Display (HTML):Batalov, Srsieve, CRUS, OpenPFGW Number of primes:total 15 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 46.2383, on current list 45.1901 (normalized score 2) Entrance Rank(*):mean 87.00 (minimum 87, maximum 87)
