Proof-code: A61

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 A61, one of those codes.

Code name (*):A61
Persons (*):1 (counting humans only)

Score for Primes (*):total 52.7867, on current list 52.7867 (normalized score 1473)
Entrance Rank (*):mean 16.00 (minimum 16, maximum 16)
