Found these (probable) primes:

(1627*9^2939+1)/4
(2007*9^3942+1)/8
(243*11^2384-1)/2
(856*11^2105-1)/5

Continue reserving...

Those are all proven by Edwin Hall.
Reserving (751*4^6615-1)/3, should take ~12K sec.

Thanks!!!

You fully proved the 2nd and the 3rd conjecture for R4!!!

I think you can prove the primality for the probable primes in the post #552 first. Some bases only need one primality proving, e.g. R17, it only needs the primality proving for the probable prime (29*17^4904-1)/4.

Current likely at n=2K, S93 has no (probable) primes found.

S93 k=67, S93 k=87 and S117 k=59 are still remain (also the half GFN's, i.e. S93 k=93 and S117 k=117).

No primes found for these k's, they are likely tested to n=8K.

Reserve R85 and R115.
