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.
