Proof-code: x30

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 x30, one of those codes.

Code name (*): x30 (See the descriptive data below.)

Persons (*): 2 (counting humans only)

Projects (*): 0 (counting projects only)

Display (HTML): Broadhurst, Dubner

Number of primes: total 5

Unverified Primes: 0 (prime table entries marked 'Composite','Untested', or 'InProcess'

Score for Primes (*): total 35.4270

Descriptive Data: (report abuse)

This code celebrates the fact that more than 30% of the digits of 10^15600-1 are factorized. Pari-GP was used to implement a Konyagin-Pomerance method for proving these palindromes prime. OpenPFGW performed the BLS tests, which were necessary but far from sufficient.

I am a member of this code and I would like to:
