Hi All, My search for >5000 digit BLS provable CPAP or triplet continues. I have now processed up to 1.4 billion (with another 300 million that are not...
... Ah, as you indicated, Hans, a triple-ECPP project. In the end, ECPP must win over BLS, since the BLS strategy that Tony Forbes initiated, that I pursued,...
I Agree, But where's the fun? The 4007 digit CPAP3 I found took a week or so using pfgw to find then 3 months processing using primo to prove. The challege was...

I recently finished a primality proof of Phi(1051,2207) (certificate posted to http://srp.stanford.edu/pp/) and got a chance to try pfgw's -x option, since I...

Hi all, I want to check, without doubt, that number is prime. Using the -t -f -q command line options (got that from the beginners guide), it tells me my...

+016 is prime! Time : 2545.317 sec. is my confirmation using the new LLR on a 2.4 GHz pentium of Jason Kowzun's recently discovered prime. Compare with...
Congrats to Jason and the 321-team. ... At the proving stage, it might be a good idea _not_ to use the fastest LLR? I recall that Chris and I detected a false...

Challenge: Post a top-5k prime of the form a^b+c^d with min(a,c)>1 and min(b,d)>2. Comment: Preda's proof of the Catalan conjecture makes this look very hard,...
