The 2nd MegaBit-Drive - 80.8% done

This page is a Summary of the 2nd MegaBit Team Drive from Riesel Prime Search.

The goal of this drive is to search for primes of the form k · 2ⁿ-1 for 19 k-values 100 < k < 200
namely k = 115, 117, 123, 129, 135, 147, 149, 153, 155, 157, 159, 171, 173, 175, 179, 183, 185, 189, 193
and 1000000 ≤ n ≤ 1100000.
