# Proof-code: L4197

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 L4197, one of those codes.

Code name(*):L4197 Persons(*):1 (counting humans only) Projects(*):1 (counting projects only) Display (HTML):Kumagai1, Srsieve, PrimeGrid, LLR Number of primes:total 1 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 47.7806, on current list 47.7806 (normalized score 28) Entrance Rank(*):mean 53.00 (minimum 53, maximum 53)
