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
All k's searched for 1400000 ≤ n ≤ 2222000.
| k-value | Nash | Candidates | # primes | prime(s) for n |
|---|---|---|---|---|
| 203 | 1687 | 23371 | 0 | |
| 205 | 1351 | 19486 | 2 | 1537779, 1666435 |
| 219 | 1069 | 14363 | 1 | 2178673 |
