Nice work, Mark, and congratulations on this impressive discovery!

Well done Mark (and Geoff and PrimeGrid)!

Primality proofs for k*b^n-1 forms require multiple BLS tests.

Congrats should really go to Lennart, the lucky finder.

because the prp test take 1/7.5 of the time the actual primality test does

And congrats to Lennart Vogel as well!
