[hide]Purpose
Searching for top-5000 Riesel primes for k = 6000 - 7000 from n = 410000 excluding k's reserved by others. 378 k's were searched.
99 known k's were excluded from the drive including all k = 6200 - 6300 out of 122 total exclusions. See exclusions here. Excluded k's are on the right side of the slash "/" shown in the 2nd batch. The remaining 23 excluded k's are unknown at this time.
- Started: 2009-05-28.
Status
- Suspended: About 2010-06-06 at approximately n = 560000.
Notes
Primes were reported in Free-DC's Prime Search thread here.
The drive formally omitted n = 485000 - 490000 per the final statement of this post. The project was known to skip forward n-ranges to keep primes in the top-5000 but often this was not stated.
An unusually small number of primes were reported in the n = 530000 - 550000 range. This likely extends to the n = 520000 - 560000 range. Some n-ranges were likely skipped for the above reason.
The suspended date is the date of the final Free-DC prime where k = 6000 - 7000 and n ≤ 560000 reported in the final 2nd drive post and at top-5000 primes.
The post here refers to the High-weight drive that was run on the same port as Drive 2. The drive was restricted to high-weight k's only.
