GIMPS has discovered a new largest known prime number: 282589933-1 (24,862,048 digits)

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 L97, one of those codes.

Code name (*):L97   (See the descriptive data below.)

Descriptive Data: (report abuse)
David Broadhurst, Wilfrid Keller, Predrag Minovic, Jean Penne and Paul Underwood worked together on testing various versions of LLR against lists of known primes, tests by OpenPFGW, and a Pari-GP implementation of the LLR test. Corrections to LLR resulted from observations of strings of zeros in residues, some of which were refuted by Pari-GP. This discoverers' code records a prime found at the conclusion of such testing.
