[quote=Siemelink;133588]Hiho everyone,

I realized yesterday that 25 = 5^2 and that I can use the primes from the base 5 search. So I've gone through all the posts on the Riesel 5 forum. I found 97 primes from the Riesel 5 search that overlap. And there are 69 k's that show up for both conjectures where no prime has been found yet.

I've attached the remaining k's.

Nice detective work Willem! Just like we use base 2 primes for bases 4, 16, and 256 and other powers of 2.

On May 16th, JapelPrime reported completion to n=230K on Sierp base 9.

Riesel Base 6:
37295*6^65412-1 is prime!

k=1597 upto 167k tested.
k=9577 upto 93k tested.
all other k's tested upto n=65k.

14 k remain for Riesel Base 6.

Excellent! Thanks Karsten.

I'm glad to see the good progress on Riesel base 6. I think it's the most important base being worked on here because it is the lowest non-power-of-2 base that is being worked on by this project that is potentially solveable in our lifetime! :smile:

If you get tired of it at some point, I'll make a team drive out of it.

KEP has sent me an Email that he is releasing Sierp base 12 and Riesel base 27. He has provided a sieved file for Riesel base 27 in the base 3 reservations/statuses thread and there is a link to it on the Riesel reservations web page.

I have asked him if he has a sieved file for Sierp base 12 also.


Gary

I moved all discussion about the Riesel base 24 algebraic factor issues to the newly renamed [URL="http://www.mersenneforum.org/showthread.php?t=10279"]algebraic factor issues base 24[/URL] thread, which includes issues related to both Riesel and Sierp base 24.

Micha, see towards the bottom of the thread about k=6 and k=486 being eliminated for Riesel base 24.

Just sent the Base 12 sierpinski to you my friend :smile: on your e-mail...

Thanks to both of you for the work on each side of Base 19. :smile:

OK, I agree that you have 46 primes here , but I show that there are 43 separate k-values that can be removed, not 41. This leaves 1582 - 43 = 1539 k's remaining at n=11.12K.

Uhhhm, weird, guess it must have been something I've missed, well maybe you will see some repeated k's that gets primed again :smile:... it's all about the eyes I guess :smile:
