Thanks, Gary, and thanks to all!
Indeed, after your last success with Riesel numbers, and after this last one, the search for solving Liskovets-Gallot conjectures becomes really exciting!
About that, I have two questions :

1) I just see that the Liskovets-Gallot page in http://www.rieselprime.de has not been updated since November 2011...
Is it still possible to ask to Karsten to do this updating? It would be really great, because huge progresses have been done, that are not shown...
2) Is it possible that I reserve now again the two Sierpinski odd n's candidates k=9237 and k=32247?
Finding a prime for these two k value would terminate the Sierpinski base 4 search, and make another LG conjecture with one k remaining!

Best Regards,
Jean

k=32247 at n=3.15M is being searched on our PRPnet port 1400. k=9267 at n=6M is available.

Thanks for the info, so, I will reserve only k=9267.

As you can see, I will now reserve k=9267 that you tested for odd n's up to 6M.
Please would you tell me up to what P value the sieved file you used was sieved, and if it contains
exponents larger than 6M? If no, I will sieve from scratch...

Best Regards,
Jean

I received sieve file from Lennart, sieve depth was 400P (done by Primegrid). 6M-9M range sieved now to p=~103P. Primegrid does not provide sieve files for +1 side for some reasons, but I think you can contact Lennart or JimB and receive it for k=9267.

Good luck in your search!

Lennart is out of reach and I suspect something bad happened.

If you're unable to get the k=9267 file, I have one but not sieved nearly as deeply. Our sieving drive sieved all base 2 odd/even/k's/n's for n=1M-16777216 to P=700T. Hopefully you can get ahold of the PrimeGrid file which is sieved > 100x more.

Many thanks, Gary!
I got the sieved file up to 760T from your drive, and will use it for k=9267 by LLR testing and sieving it upper whith a second core.

R2, k=9519 tested n=11M to 12M, nothing. Continuing...
