Proof-code: L871

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 L871, one of those codes.

Code name (*): L871 (See the descriptive data below.)

Persons (*): 1 (counting humans only)

Projects (*): 1 (counting projects only)
