# Proof-code: CH7

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 CH7, one of those codes.

Code name(*):CH7 Persons(*):1 (counting humans only) Projects(*):0 (counting projects only) Display (HTML):Broadhurst, OpenPFGW, CHG Number of primes:total 1 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 30.8974, on current list 30.8974 Entrance Rank(*):mean 51221.00 (minimum 51221, maximum 51221)

Below is additional information about this entry.
