Proof-code: CH9

Previous Next Random

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 4
Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess'
Score for Primes (*):total 47.2297, on current list 47.0680 (normalized score 7)
Entrance Rank (*):mean 1375.50 (minimum 414, maximum 2337)

Descriptive Data: (report abuse)
Some of the small factors that are used to construct F or G for CHG input file are found using ECM-6.4.3.
I am a member of this code and I would like to:
