Proof-code: L921

Previous Next Random

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 L921, one of those codes.

Code name (*): L921 (See the descriptive data below.)

Persons (*): 1 (counting humans only)
