Reserving CK14 for n=30k - 50k (using sieve from post #1) and sieving n=50k - 100k, too.

Base 54 is complete to n=30K. 1 prime was found for n=10K-30K. Base released.

Base 54 was also doublechecked to n=10K. No problems found.

CK44 complete to n=100k and releasing.
No further primes.

Reserving base 56 to n=30K.

Base 56 is complete to n=30K. 1 prime was found for n=10K-30K. Base released.

Reserving base 58 to n=30K.

Base 58 is complete to n=30K. 2 primes were found for n=10K-30K. Base released.

All bases <= 100 are now complete to n>=30K. :smile:

Base 6 is at n = 137720. No primes have been found, and I am continuing to n = 150k.
Base 10 sieve is at p = 2.75 T; progress has been quite slow due to the large n range. The target sieve depth is still 10 T.

CK14 tested to n=100k, new prime

(14^50603-1)^2-2 (115996 digits)

found and releasing

Base 12 for n = 50k - 100k has been sieved to 10 T. The sieve file is attached below:

While doing more sieving for FermatSearch, I took base 2 from 750,000 to 760,000. No new primes. Continuing.

Reserving base 18 to n = 50k.
