- Name: Riesel Prime Search 3rd Megabit Drive
- Purpose: The goal of this drive is to search for primes of the form k•2n-1 for k ≤ 300 and n > 1400000.
- Link: Mersenne Forum
- Started: 2014-05-30
- Ended: 2022-03-09
- k-values:
- 2014-05-30: k = 203, 205, 219, 227, 235, 257, 259
- 2014-06-03: adding k = 275, 295
- All for drive: k = 203, 205, 219, 227, 235, 257, 259, 275, 295
- n-values: 1400000 ≤ n ≤ 2222000
Data table
All k's searched for entire n-range.
| k-value | Nash | prime(s) for n |
