  • Name: Riesel Prime Search Drive 7
  • Purpose: The goal of this drive is to search for primes of the form k•2n-1 for 21 high-weighted 2200 < k < 3000.
  • Link: Mersenne Forum
  • Started: 2009-02-06
  • Ended: 2024-04-14
  • k-values:
2009-02-06: k = 2235, 2265, 2295, 2325, 2355, 2415, 2445, 2505, 2547, 2565,
2655, 2685, 2715, 2745, 2775, 2835, 2865, 2895, 2925, 2955, 2985 for 360,000 ≤ n ≤ 600,000
2009-08-23: removing k = 2865 for n > 600,000
2009-08-23: extending remaining k for 600,000 < n ≤ 1,000,000
2011-09-13: extending all k for n > 1,000,000
All for drive k = 2235, 2265, 2295, 2325, 2355, 2415, 2445, 2505, 2547, 2565, 2655, 2685, 2715, 2745, 2775, 2835, 2865, 2895, 2925, 2955, 2985
  • n-values: 360000 ≤ n ≤ 2000000
