Proof-code: x50

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 x50, one of those codes.

Code name (*):x50
Persons (*):1 (counting humans only)
Projects (*):0 (counting projects only)
Display (HTML):Propper, GFNSvCUDA, GeneFer, Unknown
Number of primes:total 4
Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess'
Score for Primes (*):total 51.4456, on current list 51.4456 (normalized score 337)
Entrance Rank (*):mean 154.75 (minimum 66, maximum 228)
