Don't forget to submit it.

gd_barnes, if 741*2^557981-1 needs to be submitted, have at it. :smile:

Done.

BTW, I forgot to mention...Ian has been on one of the most impressive runs of primes that we've had at NPLB for a very long time...6 top-5000 primes in < 3 days! I'm jelous. lol

He is also sieving k=1005-2000. In just a few days, he sieved it from P=160G to 240G and said he'll take it to P=1T by year end. After the 1st drive is done, we'll open a team effort to LLR the range from n=50K-500K after we discuss how the best way to break it up would be. To test it in the top-5000 range (likely n>350K by then), we'll probably need to sieve it further then P=1T though.

Thanks for the great contribution Ian! :smile:
