Purpose
The goal of this drive is to search for primes of the form k•2n-1 for k ≤ 300 and n > 1400000.
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
Data table
The data file can be found here. All k's searched for 1400000 ≤ n ≤ 2222000.
