(16*94^21951-1)/3 (currently at n=22303)

Now only k=29 needs a prime, and this k has already been searched to n=1M by CRUS, this base also released.

R97 tested to n=23113, no (probable) prime found.

R118 tested to n=24257, no (probable) prime found.

R97 at n=35817, R118 at n=37013, both no (probable) prime found.

Update files for the 1st, 2nd and 3rd conjecture for SR32 and SR64.

S32 has k=4 and k=16 remain, R32 has k=29 remain, SR64 are both proven.
