k*b^n-1 was tested there for k<=12, b<=1030 and n<=25k for a different purpose, not CRUS.

This is already done to n=100K, see post https://mersenneforum.org/showpost.p...&postcount=104 betrig

also k=b-1 and b+1 done to n=100K, see https://www.rieselprime.de/ziki/Williams_prime

R990 is complete to n=2500 as shown on the main page. It will not show up on the page that you linked here unless I list all of the k's remaining. I do not list k's remaining unless a base has been tested to n>=10K.

I missed removing that one and showing its prime when Reb reported completion of R990 to n=2500. It is now removed from the sieve file and the prime is shown.

I'm assuming you mean S837.
