Reserving k=147 from n=600696, I plan to take it to 1.5M. :smile:

k=49
 

Update:
LLR complete to 1240k.
No new primes.

13 complete to 1.3M.
201 complete to 1.0M.
93 complete to 980k.
127 complete to 1.65M.
All are still in progress.

157*2^802321-1 is prime! :big grin: (My largest yet!)

k=19 is complete to n=1206K, and I'm releasing that k.

The last time I posted residues was at n=1112K, so I'm attaching the results from n=1112K to n=1206K.

No primes were found in that range :sad:

k=37, 41, 43, 61, and 63 complete to n=965K; still going to n=1M. ETA is ~3 weeks now on 3 cores.

I see that a nice prime was found for k=63 at n>1.1M by Kosmaj. Nice find! :smile:

As you all may already know, I'm only going to n=1M on all of these so if you haven't already, feel free to take them for n>1M.

k=209 at n=870k
k=297 at n=647k

k=49
 

Update:
LLR complete to 1300k.

k=233, 263, 283, 299 tested till n=920000.
I am releasing k=263 - Curtis should have a priority on further reservation of this one.

MinMax Status Update
 

Last time mentioned [URL="http://mersenneforum.org/showpost.php?p=121536&postcount=118"]here[/URL]

The only two k<300 with largest known prime smaller than 200k bits are now:

k=283, n=149351
k=233, n=179992

Both tested to 920k and reserved by Cruelty.

I forgot to report this a couple of weeks ago:

k=37, 41, 43, 61, and 63 are complete to 1M. Primes already reported.

I'm done with these. Good luck with them everyone. They are nice low k's to test.
