Riesel Primes k*2^n-1, k<300 [Part II] - Page 93

VBCurtis · 2021-02-13, 19:16

I heard back from sjtjung. He says he has retired from prime searching, and apologises for losing his MF login info. His email linked to the forum is also dead.

Good luck with k=221.

I'll take over k=31 from sjtjung. If there is a third k reserved by him, it should be released.

gd_barnes · 2021-02-13, 21:38

k=221 is complete to n=2M; no primes were found for n=1M-2M; the k is released.

Since this was mostly a doublecheck, results were added to post #57 in the doublecheck thread.

Karsten,

As per Curtis' post, you can release k=207 and k=221 and reserve k=31 for him.

All were previously reserved by sjtjung.

kar_bon · 2021-02-14, 09:44

I've updated k=31, 207, 221, 255, 285 in the Wiki.
For k=255 included all data from that own thread (link given).

A lot of k-values <300 still reserved with last information years ago.
Perhaps a new management of this project should be considered.

I am not seeing any updates here:
https://www.rieselprime.de/ziki/Riesel_k%3D1-300

Am I looking in the right place?

You have to clear your browser cache... or append to the page link "?action=purge" and press return. This should update the cache, too.

I hit refresh multiple times over a couple hours last night and it would not update. It's updated now. Weird.

k=55 at n=2.4M.

MooMoo2 · 2021-02-25, 05:32

I tested k=19 many years ago and found that n=645555 and n=916763 were prime.

That k is now listed as available on: https://www.rieselprime.de/ziki/Riesel_k%3D1-300

so I'll be reserving it

matzetoni · 2021-02-25, 10:42

I'll reserve k=73 from n=2M. Looks like it needs some love :)

k=285 is complete to n=2M; 6 previously found primes confirmed and 1 new prime reported for n=1M-2M; the k is released.
