The 11th RPS-Drive - .% done

This page is a Summary of the 11th Team Drive from Riesel Prime Search.

The goal of this drive is to search for primes of the form k · 2ⁿ-1 for 2000 < k < 2300 (123 k-values).

Excluded k-values:
2039, 2055, 2065, 2073, 2085, 2087, 2089, 2093, 2109, 2115, 2123, 2125, 2145, 2151,
2153, 2155, 2175, 2177, 2179, 2185, 2187, 2199, 2203, 2235, 2265, 2293, 2295.

Notes:
k = 2039 (tested to n = 1000000) was excluded on 2011-09-14.
For 666666 ≤ n ≤ 700000 the range 2300 < k ≤ 3000 was tested by P.Benson and T.Ritschel (excluded
k-values: 2325, 2355, 2415, 2445, 2505, 2547, 2565, 2591, 2655, 2685, 2715, 2741, 2745, 2775,
2797, 2835, 2895, 2935-2955, 2983, 2985).
