[hide]Purpose
Searching for top-5000 Riesel primes for k = 3400 - 4000 for n = 405000 - 600000 excluding 25 k's reserved by others. Total 275 k's.
- Started: 2009-05-23.
Status
- Suspended: About 2010-06-02 at approximately n = 540000.
Notes
The reservation and detail about exclusions can be found in the reservation post. Excluded k's are on the right side of the slash "/" shown in the 1st batch. The following 25 k's were excluded from the drive:
- 3465, 3539, 3555, 3615, 3645, 3663, 3681, 3687, 3697, 3717, 3719, 3761, 3775, 3817, 3821-3825, 3833, 3975, 3981, 3991-3999
The effective search range for the drive was about n = 405000 - 540000.
Primes were reported in Free-DC's Prime Search thread here.
The suspended date is the date of the final Free-DC prime where k = 3400 - 4000 and n ≤ 540000 reported at top-5000 primes. The prime was not reported in the thread shown above.
