Hi all,

I've developed Riesel base 327. The conjecture is 696 and I've managed to get the open k's down to: 38, 62, 204, 308, 346, 370, 458 and 664. My goal is to reach n - 25,000, currently n = 22,000.

Willem.

R446 is complete to n=25K

CK=74

6 k's remaining k=10,13,34,35,55,64

Attached are the results

S450 is complete to n=25K; only k=87 & 109 remain; highest prime 54*450^6981+1; base released.

R497 is complete to n=25K

CK=82

5 k's remain k=14,28,56,62,64

Attached are the results

Only k=4 remains on both of them.[/quote]
4*440[SUP]56086[/SUP]+1 is a GFN prime (of simple x[SUP]2[/SUP]+1 variety) and S440 is proven.

Note that it was easier than could have been, because left in the sieve there were n=0(mod 4) which are Aurifeuillian composites and 2(mod 4) to be searched.

Quick question: if, say, I'm testing a base and k that can potentially produce a GFN, and I find a prime which is a GFN, will the top-5000 automatically label it as such when I submit it, or is that something I have to notice and specify myself?

You may want to ask Ian if he did that manually, or was that tag server assigned. He had [URL="http://primes.utm.edu/primes/page.php?id=94039"]one[/URL] of these [URL="http://mersenneforum.org/showthread.php?p=224404#post224404"]recently[/URL].

Mine is way too small. I got specifically interested in this very topic when Ian had his prime. Searched a few series, found nothing... (until now)

It was assigned automatically by Dr. Caldwell's verification process. I didn't have a clue as to what it was.

Serge, can you post the test results for S440, just to keep the books up to date. Thanks

OK. I have about a dozen finished series, just haven't picked the time to send them all out. Will try to zip all data tonight.

R488 is complete to n=25K

CK=164

15 k's remain k=7,28,29,31,37,58,74,86,87,95,97,116,118,133,137

Results will be emailed
