Reserving the following 1ker's to n=100K

S781, S784, S797, S803, S828

[quote=Batalov;224401]...and 406*580^22265+1 is prime.
S580 with CK 414 is proven.[/quote]

NICE!!

Along with S589 that also has CK=414, it is the largest conjecture proven on both sides for bases > 165!

Does anyone care to test some 1/2/3 k'ers for bases > 165 with CK>414 that are only at n=25K to try to beat the record?

Note: For "ranking" purposes, I would put S589 ahead of S580. S589 was proven at n=14952 vs. S580 at n=22265. Nevertheless, still an excellent proof!

Congrats on your first proof ltd! :smile:

12*919^45358+1 is prime!

Proves S919.

Reserving following Sierpinski conjectures to n<=25K:

S835 CK=474 (10 k's remaining at n=1K)
S859 CK=474 (5 k's remaining at n=1K)
