Proof-code: A20

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 A20, one of those codes.

Code name (*):A20
Persons (*):2 (counting humans only)
Projects (*):0 (counting projects only)
Display (HTML):Propper, Batalov, Gcwsieve, PRST
Number of primes:total 8
Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess'
Score for Primes (*):total 53.2174, on current list 53.2174 (normalized score 3260)
Entrance Rank (*):mean 70.50 (minimum 42, maximum 133)
