Congratulations
Kosmaj
Just what a huge prime and so close to being aesthetically pleasing! Huge congrats. I have taken 15 to 620K now, with no further primes. Regards Robert Smith

releasing k=65
I am releasing k=65, it's done until n=310k. I have sieved until 158G.
If anyone is interested in the sievefile , just let me know!

Well...I'm reserving k=65 again!!
It's quite a heavy one though!

update on k=65
k=65 has been completed until n=365000, but no new primes found It has been sieved until 200G and there are about 30000 tests left
Continuing on this k!

I suggest you sieve more, at least to 500G, or if you can to 1T. Especially if you plan to continue to n=500k. If you test on two machines, stop LLR on one and run NewPGen for a week. BTW, many k's produced one or more primes in the n=350400k range and I hope k=65 will follow the pattern! Good luck.

update on k=65
k=65 has been tested until n=380000, sieved until 400G (still sieving), and no new primes found. About 29000 k's to test until n=1M.

Recent Progress
k=55 checked to n=520k, no new primes, stopped and released.
k=165, primes for n=221667, 236051, 246426, and 325922 checked to n=350k, in progress. And finally, after almost half a year, next prime for k=77: 77*2^8557701 is prime (257615 digits) k=77 checked to n=857k, in progress.

k=65 update and new reservation
k=65 has been tested until n=395000, sieved until 500G and no primes found.
I am also reserving k=149 to test until ...? Let's hope I'll find a prime for this one! :) The top5000 says that this k has primes for n=212460, which isn't listed on the progress site Last fiddled with by Templus on 20050629 at 21:42

Templus,
149*2^2124601 was found by L70, Mr. Yamada, who doesn't report either to us or to Dr. Keller. [In February, together with two other persons he found a huge Proth prime 7*2^1491852+1 with almost 450,000 digits!] So we don't know what n's he checked. I don't think he went far beyond n=230k but he definitely has resources to go much further. I'll try to contact him and I ask him. I don't have his email address but I know a person who does. But k=149 has low weight and to n=212460 only 12 primes have been found. Of course the next prime can be very close but more likely it's in the 400600k (?) range. If you want to find some primes faster I suggest k=93 or k=99, both checked only to 210k, with higher weights and many primes already found. In any case, good luck!

Well...in that case I'll go check k=93
Thanks for your input! :)

update on k=65 and k=93
Hi all,
k=65 has been checked until 418000, sieved until 550G (still sieving) and there are 27000 numbers left! Unfortunately, there are no new primes! I don't know what's wrong with this k, but when I find a prime, it will be quite a huge one! I saved all the RES64 numbers, so it can be doublechecked later if needed. k=93 has been checked until 250000, sieved until 70G. I am working on it.
