I have to do this one:

Reserving R452 to n=25K.

Even though it has 5 k's remaining at n=5K with no primes since n=1K, at CK=59 it has the lowest remaining CK of the untested bases.

Reserving R416 to n=25K.

Sierp 397
 

Sierp Base 397
Conjectured k = 10546
Covering Set = 7, 31, 37, 199
Trivial Factors k == 1 mod 2(2) and k == 2 mod 3(3) and k == 10 mod 11(11)

Found Primes: 3148k's - File emailed

Remaining: 42k's - File emailed - Tested to n=25K

Trivial Factor Eliminations: 2077k's

MOB Eliminations: 5k's - File emailed

Base Released

R416 is [URL="http://mersenneforum.org/showpost.php?p=222029&postcount=670"]done[/URL] to 34K and released.

R277 is done to 25K. 40 [I]k[/I] remain. Results emailed. Base released.

R452 is complete to n=25K; 1 prime found for n=5K-25K; 4 k's remaining; base released.

I don't appear to have received an Email on this one.

[quote=rogue;220167]Rerserving these single k conjectures:
64*259^n+1
55*266^n+1
4*335^n+1
10*341^n+1
20*401^n+1
14*334^n-1
22*347^n-1[/quote]

I completed most of these to n=100,000. I never started S401, so I am throwing that one back into the mix. I already reported a prime for S266. I have attached residues for the rest.

Note to Gary: The sieve files posted on the reservations pages are used up except for 64*259^n+1 and 20*401^n+1.
The 1k thread has been adjusted accordingly.

S257
 

All three k's (k=4, 34, 40) tested for n=25k-50k.

34*257^33062+1 is prime!

Stopping here. Results sent.

Hmm, I thought I had this reserved...Gary suggested a while back that I include it with my current batch of 2/3-k bases and provided me a sieve file for 25K-100K. It's currently loaded into my private PRPnet server and waiting to be worked on. I see it's marked on the Sierp. conjecture reservations page so I'm not sure how the confusion came about.

Since I've still got a good sieve file for 50K-100K, I'll remove the 25K-50K portion (and all of k=34) from my server and continue with the rest as planned.

Sorry for that, but I was not aware of this! There's no reservation on the Sierp-page!

PS: Oh, I noticed the error: the reservation is on [url=http://www.noprimeleftbehind.net/crus/Sierp-conjecture-reserves.htm]Sierp-Res[/url] but not on [url=http://www.noprimeleftbehind.net/crus/Sierp-conjectures.htm]Sierp-Conj[/url].
Was that meant to be so? No note on the Conj-page if there exist reservations?
