# Proof-code: L3972

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 L3972, one of those codes.

Code name(*):L3972 Persons(*):1 (counting humans only) Projects(*):1 (counting projects only) Display (HTML):Clark, PSieve, Srsieve, PrimeGrid, LLR Number of primes:total 41 Unverified Primes:0 (prime table entries marked 'Composite','Untested', or 'InProcess' Score for Primes(*):total 47.7467, on current list 44.4588 (normalized score 1) Entrance Rank(*):mean 4273.00 (minimum 4273, maximum 4273)
