  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 CH9, one of those codes.

Code name (*):CH9   (See the descriptive data below.)
Persons (*):1 (counting humans only)
Projects (*):0 (counting projects only)
Display (HTML):Zhou, OpenPFGW, CHG
Number of primes:total 1
Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess')
Score for Primes (*):total 43.8637, on current list 43.8637 (normalized score 1)
Entrance Rank (*):mean 3201.00 (minimum 3201, maximum 3201)
