When I add the new k's to the server, I will add the ranges of n=32,000 to 250,000. (Removing everything below n=32,000 - I can't fix the sieve right now because I don't have access to the machine until Monday... :)

I'll post the k=65 primes sometime tomorrow.

And if possible, I'll move the LLRnet server to a linux machine tomorrow night.

[QUOTE=Kosmaj]Then let's test them all to 32k, thus completing all double-checks off the network. Just tell us the status and let's divide the work, either by k or by n. I tested them all to 10k (see above).

BTW, I'd also like to reserve [b]k=77[/b] to test by myself to n=250k.[/QUOTE]

lets sieve all the k's upto 1M and then use LLR to bring all of them upto 32K.

If, some one could do this and make a file with all the k's in it then we can divide that file easily.

Results for 85, 97 and 179
 
Hi all,

I have finished testing k=85, 97 and 179 up to n=200000.

k=85: 5, 11, 71, 113, 115, 355, 473, 563, 883, 1235, 5735, 9809, 11311, 14491, 25495, 125675, 128459, 147115

k=179: 8, 68, 108, 20780, 25488, 25656, 38684, 57096, 159108

I am still testing k=193, but I would like to reserve k=171, 183 and 225.

k = 49
 
I have stopped testing at 417500 with no new primes. k=49 is now open to whomever wants it.

rogue 2004-06-07 20:20

k=49
 
I am unable to send e-mail to Wilfrid Keller as his e-mail server has blocked all e-mail from Road Runner. Could someone please send him information on the current status of k=49?

Thanks.

Just give him the link of our status page. He'll be free to update when ever he wants.

k=79 Done
 
k=79 checked 20000-250000, primes found for n = 65977, 82081, 92517, 214453, and 248055.

BTW, what's the status of k=53? It looks abandoned at n=89850. If nobody is working on it, I'd like to reserve it.

I'll mail Dr Keller about k=49 and 79 and will tell him about the page maintained by Joss.

And finally congrats to everybody on new primes, but in particular to "our" [B]Keller[/B] on his first primes (k=75) in Top-5000! :cool:

Thanks.

k=81 is done till 220K and Im stopping there.

No new primes.

No problems. I just mailed Dr Keller about k=49, 63, 65 ("15k*2^n-1 Search" group) and k=79. Only now I noticed that large primes for k=65 have been already reported by others :sad: I also told him about the page by Joss but I'm afraid we still have to mail him because on the page we have our nick-names while he prefers real names, it's not stated who processed k's marked as "Done" etc.

Joss, on your list you are missing 63*2^1792-1, it's on Keller's list and it's prime, I just checked.

Happy hunting to all!

My real name is Mark Rodenkirch, but you probably could have figured that out by looking at who took credit in the Prime pages.
