# Proof-code: c4

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 c4, one of those codes.

Code name(*):c4 Persons(*):1 (counting humans only) Projects(*):0 (counting projects only) Display (HTML):Broadhurst, Primo Number of primes:total 109 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 35.3617, on current list 34.0704 Entrance Rank(*):mean 44125.36 (minimum 28287, maximum 66294)

Below is additional information about this entry.
