Marcel Martin's Primo

program

A titan, as defined by Samuel Yates, is anyone who has found a titanic prime. This page provides data on those that have found these primes. The data below only reflects on the primes currently on the list. (Many of the terms that are used here are explained on another page.)

Descriptive Data: (report abuse)

Primo is a program that will test numbers that are not of any special form. This is far more difficult (and slower) than doing so for primes n with special forms (e.g., those where n+1 factors nicely).

Primo is a primality proving program based on the ECPP algorithm: Elliptic Curve Primality Proving. Given positive odd integers, Primo tests whether these integers are prime, and if they are it produces primality certificates. Primo is suitable for the checking of crypto-primes and to prove whether they are actually prime... or not.

Surname: Primo (used for alphabetizing and in codes).
Unverified primes are omitted from counts and lists until verification completed.
