Because there was a ton of them, and even more with >29% (which I didn't submit). The comment there says it all (they are a dataset for anyone who wants to learn CHG in practice). The real search...

Skipping a few intermediate records, here is one that could be a decent candidate for someone with the next version of Primo: 10^31047-2*10^26802-1 is prime and 10^31047-2*10^26802-3 is a Fermat...

And here is its evil twin: i.e. all digits are "7"s, except for one and two "9"s. (7*10^10014+18*10^3046+11)/9 (PRP) and (7*10^10014+18*10^3046-7)/9 (PRP) ECPP proofs are in progress. There...

Views: 12,351 Posted By Batalov a NeRDs-related twin pair A small but elegant twin pair (using one "7" and two "7"s, with the rest of digits being "9"s): 10^4621-2*10^4208-1 is prime 10^4621-2*10^4208-3 is prime (Prime certificate is available)

The records in CHG are not in the size but the % factored part, and I've played with that some years earlier. Among other things, I have proven a relatively uninteresting, artificially constructed...
 Forum: NeRDs 2014-11-08, 17:26 Replies: 15 Sticky: Primes found! Views: 12,351 Posted By Batalov Two primes for the 388080 series Overnight, one iteration of CHG came through! Now, there's a good chance that we will have a proof (based on the %-age, we will need maybe 6-7 iterations; and I sacrificed factors of N-1 to make the...

I have one, and it's a toughie: only 29% factored N+1. Will have to give it a crack with CHG.gp script. (I've proven some primes with CHG before, but never this big. The...
