RPS Drive 7

• 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 360000 ≤ n ≤ 600000

2009-08-23: removing k = 2865 for n > 600000

2009-08-23: extending remaining k for 600000 < n ≤ 1000000

2011-09-13: extending all k for n > 1000000

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
