Exclusions:
k's that are multiples of the base where (k+1)/gcd(k+1,b1) (+ for Sierp,  for Riesel) is not prime.
I'll give some examples for S22:
k=44, 154, 220, 242, 264, 374, 440 would be excluded from testing because 45/3, 155, 221, 243/3, 265, 375/3, 441/21 are not primes.
k=22, 66, 88, 110, 132, 176, 198, 286, 308, 330, 352, 396, 418 would be INcluded in testing because 23, 67, 89, 111/3, 133/7, 177/3, 199, 287/7, 309/3, 331, 353, 397, 419 are primes.
The exclusions for multiples of the base are the same on all bases. Check for (k1)/gcd(k+1,b1) being prime on the Riesel side and check for (k+1)/gcd(k+1,b1) being prime on the Sierp side. If it's prime, include it; if it's not prime, exclude it.
