Reserving Sierp Base 95 to n=25K

[quote=MyDogBuster;203129]Reserving Sierp Base 95 to n=25K[/quote]

That ones looks a bit unpleasant. :-) It also reminds me that I have it in my head to take Sierp base 97 from n=10K to 25K. (But I'm not reserving it just yet.)

Within a couple of weeks after my Sierp base 31 finally finishes to n=25K (with ~1105-1110 k's remaining), I'm going to reserve perhaps 3-4 bases < 200 that have been already tested but are at n<25K. I'll exclude both sides of bases 39 and 40 from that. :smile: I've had enough of the 1100+ k's on Sierp base 31 that I don't really want to test anything with more than 300-400 k's remaining at n=10K or 15K right now.

Max, are you still working on Sierp base 39? I think you were going to take it from n=10K to 15K. Just curious.

I need to follow up with Ozzy on Sierp base 117, which has 8 k's remaining but only tested to n=10K and has been dormant for 6 months. I think I'll PM him shortly.

If I had to recommend some work to people, take a look at all bases < 200 that have already been started but are still at n < 25K and unreserved. I think there's a couple of them that shouldn't take too long to bring up to n=25K.

Yep, still working on it. I'd had to put it on hold for a while due to CPU heat problems but I'm back on the trail. It seems to be proceeding quickly enough--it's at 10.5K after a total of about 1.5 CPU days of work on it.

R91 is at n=10K; 123 k's remaining; continuing on to n=25K.

Cleaning out the closets now.

I'm reserving some k from Riesel 36 from n = 25,000 to 100,000.

Riesel base 58
 

Finally completed this base to k=50000 and am releasing it. This is one of the biggest single efforts I've had in a long time. Here are the primes found since k=40000:

17 unique k's with primes leaves 313 k's remaining at n=50K.

Yes, that was some huge effort! Are you ready to do Sierp 58 to n=50K now? :smile:

:shock: No!
