[quote=MyDogBuster;216462]Reserving the folllowing "1ker's" to n=50K.

30*514^n-1
22*900^n-1
8*908^n-1
74*947^n-1
4*968^n-1[/quote]

22*900^n-1 was done to n=100K by me.

I can't find a post for R900 to n=100K. I see you did S900 as proven. Would you still have the files for R900?

unconnected 2010-05-28 20:46

I was going to post results for R900 together with R888 and R800 which also has reserved. They will be ready in 2-3 days.
I like "round" bases :smile:

Yeah, I noticed you like the round ones...100, 200, 300, etc. :-)

If you have a reservation for R900, I must have missed it. Until you report the official status/results, I'll show it at n=25K and reserved by you to n=100K.

S928
 
Update on S928: complete to 12K

The following are primes:
[CODE]14128*928^11074+1
11518*928^11143+1
23712*928^11280+1
3484*928^11445+1
5547*928^11446+1
5799*928^11475+1
5253*928^11527+1
3934*928^11553+1
25203*928^11671+1
26503*928^11675+1
23113*928^11791+1
7828*928^11795+1
11493*928^11840+1
20523*928^11848+1
18808*928^11968+1
12156*928^11071+1
[/CODE]

16 primes, takes down to 648k-values remaining. Woo.

Continuing.

Riesel base 928 update
 
I have been going a little further on this range with my testing of PRPNet 3.3.0. I have found these primes:

27882*928^17164-1
8958*928^17378-1
24201*928^17447-1
11003*928^17454-1
12245*928^17484-1
21576*928^17495-1
8474*928^17505-1
15051*928^17510-1

I'm continuing on.

OK, since you're continuing, I should say this: Before posting the sieve file on the web pages, I found something like 5-10 k's in the file that you sent me from last time that already had primes for them so I used srfile to remove them before posting it.

Therefore if you are not using the file that I posted on the pages and did not remove any additional k's from the file since the last time you stopped, you can save some CPU time by using my file and removing the k's where you found primes here.

2 things I always do before posting sieve files on the pages is check the # of k's in them and their sieve depth, if that depth is either not available or looks unusual.

I'll take a look and remove the k's that I had not removed from the server.
