Nice work Xentar!

For S19, 75 primes for n=54K-70K leaves 773 k's remaining at n=70K.

[MyDogBuster]

R27 tested to n=850K - nothing found - continuing to 1M

[Cruelty]

Base=10 (Sierpinski + Riesel) tested till n=710000

[Mathew]

R19 is complete to n=50K

267 primes found

Base released

[Puzzle-Peter]

R31 tested n=250k to 300k, no luck. Continuing...
