Thanks!

I'd say a good starting point for some sieve files would be bases 52, 54, 56, and 58 for n=10K-30K. I feel like P=300G would be sufficient. Although these bases are only searched to n=10K, all other bases around them have already been searched to n=30K.

All of these bases are completed to n=10K, primes reported in other thread, bases released.

Bases 364 and 368 have Carol prime found, and base 426 has Kynea prime found.

Bases 362, 394 and 472 still have no Carol prime found.

The number that I am factoring has entered LA, so I will reserve bases 52, 54, 56 and 58 for sieving, from n=10k to n=30k.

The n-range of 10k-30k has been sieved for bases 52, 54, 56, and 58 up to p = 500G, which was when the time to remove a factor became longer than the time needed to test any candidate in the files. They are included in the 7zipped file attached in this post.

Reserving base 10, n = 100k to 200k, for sieving.

Thanks Dylan. I have added the files to the first post in this thread.

ck update 3/11

Base 6 is at n = 130207. No new primes have been found yet, and I am continuing to n = 150k.
Base 10 sieving is at p = 1.05 T. Goal is to get the sieve file sieved up to p = 10 T or so (maybe less depending on the time per factor).
Lastly I have two more sieve files: base 14 for n = 30k to 50k (sieved to 1.2 T) and base 18 for n = 40k to 50k (sieved to 2 T). Both files are attached in the 7 zipped file in this post.
As an aside, when these files have been fully tested, all bases <= 20 will have been searched to n >= 50k.
