- Name: Riesel Prime Search 1st Megabit Drive
- Purpose: The goal of this drive is to search for primes of the form k•2n-1 for k ≤ 300 and n > 1000000.
- Link: Mersenne Forum
- Started: 2010-10-24
- Ended: ongoing
- k-values:
- 2010-10-24: k = 51, 57, 61, 65, 69, 87 for n > 1,000,000
- 2011-01-26: adding k = 47, 53 for n > 1,000,000
- 2014-08-12: removing k = 51, 69 for n > 2,500,000
- 2014-08-12: adding k = 35 for n > 2,520,000, k = 37 for n > 2,500,000 only n != 1 mod 10, k = 103 for n ≥ 2,550,223, and k = 111 for n ≥ 2,601,487
- currently k = 35, 37, 47, 53, 57, 61, 65, 87, 103, 111
- n-values:
- n > 1000000
Sieve file
Sieve file for 3,000,000 < n < 4,000,000 available here (LLR-format, 291,383 candidates).
