The 5th RPS-Drive - The range overview table/primes are not complete yet

Started: 2007-11-21 Last update: 2009-01-07

This page is a Summary of the 5th Team Drive from Riesel Prime Search.

The goal of this drive was to search for primes of the form k·2ⁿ-1 for 14 k's < 300 divisible by 3:

Beginning at n=870k k=51 and k=57 were omitted because they were already tested to n=1.0M after higher primes were found.

Basic information:

Status	The drive is over!
