Another lot. Last for at least a couple days.
S258, CK=36, Base proven.
S264, CK=54, Two ks remaining.
S266, CK=88, One k remaining.
Primes attached.
Bases tested to 25k and released.

An easy one:
S362, CK=10, proven.
Just one base, so here are the primes:
2*362^15+1
3*362^1+1
4*362^30+1
5*362^1+1
6*362^9+1
7*362^6+1
8*362^1+1
9*362^1+1

Great to see the Sierp side getting worked on now. It definitely needed some work.

k*324^n+1 (conjectured k of 14)
k*339^n+1 (conjectured k of 16)

Oops my bad.

Too early to be doing typing.

Sierp Base 338
Conjectured k = 112

Trivial Factors k == 336 mod 337(337)

Found Primes: 97k's - File attached

Remaining k's: 13k's - File attached - Tested to n=25K

Base Released

k = 1 is a GFN with no known prime

Testing out the new-bases script (having never attempted a base from scratch before.)
Reserving Sierp 395 with conjectured k=10 to n=25K.

R328 is done to n=150K. One prime. Base released.
