Found the conjectured smallest Sierpinski/Riesel numbers for bases <= 2500
* Only the k's with covering set are considered as Sierpinski/Riesel numbers, kvalues that make a full covering set with all or partial algebraic factors are excluded from the conjectures.
* Searched to k=5M, listed "NA" if the conjectured smallest Sierpinski/Riesel number for this base is >5M (i.e. there is no k <= 5M with covering set)
* Test limit: primes in the covering set <= 100K, exponents <= 2100
