Proof-code: CH15

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 CH15, one of those codes.

Code name (*):CH15
Persons (*):2 (counting humans only)

Score for Primes (*):total 40.6003, on current list 40.6003
Entrance Rank (*):mean 56522.80 (minimum 54560, maximum 57689)
