# Proof-code: L257

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 L257, one of those codes.

Code name(*):L257 Persons(*):1 (counting humans only) Projects(*):1 (counting projects only) Display (HTML):Ritschel, Srsieve, Rieselprime, LLR Number of primes:total 132 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 47.0776, on current list 46.3879 (normalized score 7) Entrance Rank(*):mean 1032.33 (minimum 369, maximum 1420)
