I guess it's about time I found out what these critters are. <rummage rummage>

There is a most recent update on 2018-10-16 by kar_bon for base 12 at Carol and Kynea Prime Search. I'm guessing the two largest ones are the newest. These would be (12^68835 - 1)^2 - 2 and (12^78858 + 1)^2 - 2.

I'll provide the files later this week as I am away from home.

This file is for Dylan14. It is only the n/c that haven't been tested below 1000000. You can easily generate the first line for base 2 using cksieve.

Thanks for the sieve file rogue. By the way, the start of the file is at 765831. Did you test the numbers between n=760k and the start of the file, or is that a gap that I will need to fill in?

As I stated these are the only candidates that haven't been tested, so anything below the n in the file was either removed by sieving or by testing.

Base 2 is at n = 765831. No primes have been found yet, continuing.
Base 6 sieve is at p = 22.25 T. I will sieve this to 60 T, this should be done before the next monthly update.

CK290 at n=113k
CK362 at n=100k

and continuing

[Dylan14]

Base 2 is at n = 768870. No primes found yet, continuing.
Base 6 sieve is at p = 39.25 T. Target is still 60 T.
Also running a sieve for base 50 for n = 120k to 150k, it is presently at p = 9 T.
I am also wondering what goals this project should have for next year (find a T5k prime, get all b <= 50 to n = 100k, etc.).
