- Name: Riesel Prime Search Drive 5
- Purpose: The goal of this drive is to search for primes of the form k•2n-1 for k ≤ 300 where k divisible by 3 and n > 260000.
- Link: Mersenne Forum
- Started: 2006-11-12
- Ended: 2008-07-04
- k-values:
- 2006-11-12: k = 51, 57, 117, 129, 135, 213, 237, 249, 261, 267, 273, 279, 285, 291. See n-values by k in Data table below.
- 2008-01-03: removing k = 51, 57 for n > 870000
- n-values: 260000 ≤ n ≤ 1000000
