RPS Drive 8
- Name: Riesel Prime Search Drive 8
- Purpose: The goal of this drive is to search for primes of the form k•2n-1 for 20 high-weighted 3000 < k < 10000.
- Link: Mersenne Forum
- Started: 2009-03-24
- Ended: 2024-04-10
- k-values:
- 2009-03-24: k = 3345, 3975, 4935, 5025, 5355, 5445, 5535, 5865, 6165, 6369,
- 6555, 6705, 6975, 7215, 7245, 8235, 8295, 9015, 9075, 9441 for 380000 ≤ n ≤ 700000
- 2009-03-28: removing k = 8235 for n > 405000
- 2010-07-11: extending remaining k for n > 700000
- 2011-09-13: extending all k for n > 1000000
- All for drive k = 3345, 3975, 4935, 5025, 5355, 5445, 5535, 5865, 6165, 6369, 6555, 6705, 6975, 7215, 7245, 8235, 8295, 9015, 9075, 9441
- n-values: 380000 ≤ n ≤ 1333000
