This table keeps track of Riesel k < 300 reservations. Feel free to reserve an unreserved k.

k=19 is complete to n=5.073M with no primes found, and the results are attached. I'm continuing with this k.

Somewhat interesting fact: it takes slightly longer to test n=5M to n=5.073M than it takes to test n=1 to n=1787500 (the double-check residues are at: https://www.mersenneforum.org/showpo...8&postcount=71 )
