I am Nathan from email. May I finish and reserve Riesel base 79 from 50K to 60K?

OK I will mark it down for you.

Please report all primes and send me the residues file when you are done.

Taking R36 from 250k to 400k. I have a new (well, used) 12-core workstation coming this week, this is a nice big project on which to break it in.

Thanks to Masser for a very extensive sieve! (100T already).

Those who don't mind used equipment should have a peek at Ebay for Z600 model HP workstations. Lots of silicon, cheap.

I believe I understand why the sieve file is in base 6; 36 being 6-squared and all.

But why are there odd powers of 6 in the sieve file?
