Bases 4-32 reservations/statuses/primes

[mdettweiler]

I'm reserving two Sierpinski Base 16 k's: 2908 and 4885. I'll be starting the sieving on them shortly.

[gd_barnes]

I am reserving Riesel base 6 and will take all k's up to n=25K. This one is not as bad as I thought it would be. I've now taken it up to n=7K with only PFGW without sieving and there are only 43 k's remaining.

I will also reserve a couple of others and take them somewhat higher:

Sierp base 11 to 100K to finish out the remainder of the sieve file. It's currently at n=87K.

Sierp base 23 to n=60K to bring it up to where Riesel base 23 is. It's currently at n=34.5K.

Hello Gary,

Congrats for organizing this search!
I am working alone on the Riesel base 4 candidates for a while, so I wish to reserve all the divisible by 3 k's candidates, up to n = 131072 base 4 for now...

The remaining k's I wish to reserve are :

9519, 13854, 14361, 16734, 19401 and 20049, which are marked as available on your reservation page. I already eliminated all the others...

Regards,
Jean

Hi Jean,

Thank you and welcome to the effort! It's nice to have you on board. The k's are available and I will show them reserved by you today. It looks like you're now the official base 4 person; both Riesel and Sierpinski!

If you have the time, come vote in our poll in the lounge here.

Sieving on both k's has finished. I took both up to about 1.2G with srsieve, then did each individually with sr1sieve. k=2908 reached double optimal depth (i.e. factors were taking twice as long to find as an LLR test) at about 121G (I would have stopped it earlier, but it was going so fast I didn't notice it in time.) k=4885 was stopped at about 207G. It was a little ways over optimal depth, not quite as far over as k=2908, but sieved very nicely nonetheless.

I've combined the two sieve files into one, and am now running LLR testing. No primes yet...but then of course, I just started.

Haliho, here is what I have at the moment:

1611*22^n+1 completed upto 100,000, I'll take it to 200,000
5128*22^n+1 completed upto 100,000, I'll take it to 200,000
4233*22^n+1 completed upto 75500, I'll take it to 100,000

4233*22^n+1 completed upto 100000, unreserving
3104*22^n-1 completed upto 100000, unreserving
3656*22^n-1 completed upto 100000, unreserving

I've sieved and run 1422*28^n-1 until 25k. No primes there.
I am starting a new sieve on 288*13^n-1, I'll take it to 100,000


I found some PCs before I could sieve so I am reserving some of Gary sieve files:

The riesel 23, the riesel 26 and the sierp 26 file

Having fun, Willem.

I'd say you're having fun! Thank you for the detailed update, Willem. n=200K for base 22 will be quite an accomplishment when you get that done!

On those sieved files, please check the testing limit on the web pages. I was thinking that I did a little more testing on one of the base 26 files since I posted those files. (Sorry if you started already) The web pages are up to date as of about 5:00 PM GMT today (11 AM CST U.S.).

Edit: I just now noticed this: You said you're sieving 288*13^n-1. I have a posted sieved file in the sieving thread for that up to n=100K. It's sieved to P=400G, which I'm thinking is far enough. If not, at least it'll save you some sieving time.

I'm still around on the Sierpinski side of things....granted I'm really slow...but I'm still around. people are free to reserve any range they want but since no one has stepped forward I keep slowly going forward with it...

64494 is at 1770506 and still no prime

Thanks for the update Tcadigan. I'll put you down for testing completion of n=885.2K base 4. I had previously noticed that you were searching one k for Sierp base 4 so sorry about the omission there.

If you'd like to pick up a smaller search effort that also LLR's as fast as base 2, we've got 55 k's for Sierp base 16, all tested to just n=25K that are ready for testing. At some future time, we also want to start on Riesel base 16 from the beginning.


Thanks,
Gary

I have completed Riesel Base 6 to n=25K and am unreserving it. There are 19 k's remaining and ready to be reserved. See the web pages. With it being a smaller base, it won't be too intense of an effort to take them to n=100K.

I also got an Email from Michaf 2 days ago. On Sierp base 24, he was up to n=7.3K with 239 k's remaining and is sieving them all to n=100K. Pages are updated and k's remaining will be shown later. So we may have plenty of work coming from that.

Ah yes, I forgot to check your sieve files, I did download them. Can you put up a link to the sieve file from the reservation page? Then we would have a practical place to keep the sieve files.
I like sieving so I'll switch to another. I'll take 258*27^n-1

Laters, Willem.
