Well, I do intend to take this to the end of the sieve file if necessary...

How many tests are in the range you have reserved?

[QUOTE=rogue;290483]How many tests are in the range you have reserved?[/QUOTE]

~38k candidates left

k=9519 tested 5M to 6M, nothing. Continuing...

I think that before anyone takes on one of these k they should consider sieving with ppsieve. Jean's files are only sieved to 5e13. I think that 1e15 should be attainable with ppsieve.

Gary, could you edit the first post of this thread to list the remaining k for this conjecture and their test limits along with a link to the pre-sieved files for them? I know that one could find this information through the reservation pages, but one has to look at multiple places to collect that information.

Maybe later next week. I'm out of town now with little time for misc. admin stuff.

I thought ppsieve slowed down in relation to the maximum k. This make it useless unless you are sieving consecutive ks starting very low.
Do you mean withdraw the correct tests from primegrid's base 2 sieve file? AFAIK their files only go upto k=10k.

I don't know. One would have to compare ppsieve with a single k to srsieve. The problem is that Jean's files are base 4, not base 2. One would have to convert to base 2 before testing with ppsieve.

I took what I could find and put this table together. I included PSP and ESP, which you can remove if desired. If you use this as the first post, you might want to clean up the thread a little.
