This table keeps track of Riesel k < 300 reservations. Feel free to reserve an unreserved k.

k=19 is complete to n=5.073M with no primes found, and the results are attached. I'm continuing with this k.

Somewhat interesting fact: it takes slightly longer to test n=5M to n=5.073M than it takes to test n=1 to n=1787500 (the double-check residues are at: https://www.mersenneforum.org/showpo...8&postcount=71 )

k=19 is now complete to n=5.176M with no primes found, and I'm continuing with it. The results are attached.

Side note: The status page at: https://www.rieselprime.de/ziki/Riesel_prime_2_19 states that k=19 is complete to n=5482000, but this is incorrect. It's k=39 that's complete to n=5482000, not k=19. That link, the link at: https://www.rieselprime.de/ziki/Riesel_prime_2_39 , and the overall status page at: https://www.rieselprime.de/ziki/Riesel_2_1-300 need to be updated.

Thanks for finding that. I don't normally make silly importing errors like that.

No problem!

Anyway, I saw that the first two links have been fixed, but the status page at: https://www.rieselprime.de/ziki/Riesel_2_1-300
still shows the really old limits (n=5000000 for k=19 and n=5256000 for k=39). Would you be able to fix that link as well?

In my experience with independent MediaWiki wikis, logged-in users will always see an up-to-date version of a page, while logged-out users will usually see a cached version. I just purged the cache on that page, so hopefully Moo will see an updated version next time. If you run into a similar issue in the future, append ?action=purge to the URL.

That worked, thanks!
