# Proof-code: L4920

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 L4920, one of those codes.

Code name(*):L4920 Persons(*):1 (counting humans only) Projects(*):1 (counting projects only) Display (HTML):Walsh, GFNSvCUDA, GeneFer, AthGFNSieve, PrimeGrid, LLR Number of primes:total 12 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 47.0799, on current list 47.0799 (normalized score 14) Entrance Rank(*):mean 2413.58 (minimum 2247, maximum 2919)
