- Here is a new AP7 record at 1328 digits:-

(1246733996+35777939*n)*3109#+1 is prime for n=0..6

All confirmed prime with PFGW -tc

Input/output statistics:-

Numbers tested by NewPGen: 1*10^9

NewPGen reduced these (by sieving to 4 trillion) to: 2.78*10^8

PRP's found by PFGW: 2,067,593

AP6's found: 204

AP7's found: 0

The AP6's were all extended upwards and 1 AP7 found.

The search program was terminated at this point, about half way through.

Run-time statistics:-

NewPGen: 19 GHz-days

PFGW: 204 GHz-days

Pascal program to find AP7: 10 GHz-hrs

The expected AP6 count to get one AP7 was about 300.

Nice job (7 times over)!

It's such a big site I find it hard to find the right format.

What I typed was my 3rd attempt at getting it accepted.

Perhaps a "Help" comment on the submission page to refer to the "Official Comment" entry on a similar prime, like this one:

http://primes.utm.edu/primes/page.php?id=91154

would make it less likely for CC having to edit people's submissions?

Anyway, sorry, Chris.

Mike - Hi Mike

Just noticed this.

congratulations.

Looks like your AP10 record is safe.

I've been looking at n*653#

Found all primes between n=1e9 and 2.5e9 and extended all aps from 6 and up.

No luck yet with only about 10% left to test

cheers

Ken
