GIMPS has discovered a new largest known prime number: 282589933-1 (24,862,048 digits)

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 CH8, one of those codes.

Code name (*):CH8
Persons (*):1 (counting humans only)
Projects (*):1 (counting projects only)
Display (HTML):Batalov, Ksieve, TOPS, LLR, OpenPFGW, CHG
Number of primes:total 1
Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess')
Score for Primes (*):total 43.7266, on current list 43.7266 (normalized score 1)
Entrance Rank (*):mean 3563.00 (minimum 3563, maximum 3563)
