Nice. Huge one.[/QUOTE]That's the [url=https://www.mersenne.ca/userfactors/pm1/1/bits]second-biggest P-1 factor[/url] ever!

I just noticed.:jvang:

I was just getting a little frustrated with this range. Not alot of factors overall

Well done. Very smooth too!

How was this missed by firejuggler?
 
[url]https://www.mersenne.org/report_exponent/?exp_lo=14632711&full=1[/url]

K=2^3 × 3 × 17 × 43 × 349 × 2393 × 2827673

This is in no way a criticism of firejuggler but a question about the reliability of either the software or hardware.

hmmm here is my mE632711 file to see if there was any problem. It was the first 14.6M exponent I did.


I just redid it and I found the factor.

there is about 30 NF pm1 with the b1=800k and b2=179434710.
I'll rerun them

You may not have to .
I have a computer that due to a cranial malfunction is running P1 in 14.6.
I've already redone a few of your 800000s.
I'm away for 12 more days so I can't stop it unless I can talk my son into it.

Thank you. I'll let your computer do the job.

Yeah!
Good work
