Purpose
The goal of this drive is to search for primes of the form k•2n-1 for k ≤ 300 and n > 1000000.
Started
- 2011-04-28
Ended
- 2022-04-10
k-values
- 2011-04-28: k = 115, 117, 123, 129, 135, 147, 149, 153, 155, 157, 159, 171, 173, 175, 179, 183, 185, 189, 193 for 1,000,000 ≤ n ≤ 1,100,000
- 2011-06-03: extending all k for n > 1,100,000
- 2015-06-19: adding k = 131, 133, 137, 139, 141, 143, 145, 161, 177, 181, 187 for n > 2,000,000
- 2020-03-20: removing k = 193 for n > 2,200,000
- All for drive: k = 115, 117, 123, 129, 131, 133, 135, 137, 139, 141, 143, 145, 147, 149, 153, 155, 157, 159, 161, 171, 173, 175, 177, 179, 181, 183, 185, 187, 189, 193
