[QUOTE=ET_;302796]And we all send our new found factors to Will Edgington...[/QUOTE]Oh? I don't think most of us knew we did... :unsure:

[QUOTE=KyleAskine;302769]I agree. As far as I can tell you offer nothing worthwhile to the project. Especially when compared to what Chris has done.[/QUOTE]

[QUOTE=chalsall;302770]Thanks guys. But don't sweat it.

Those who can't, talk.... :wink:[/QUOTE]
Enough of your mindless insolence already

I found a 167.9 bit composite factor: [URL]http://mersenne-aries.sili.net/exponent.php?exponentdetails=8414383[/URL]

I'd say "nice two!"

Not too long ago, a few people explained to me the percentages between stage 1 and stage 2 of P-1 how factors are found. Knowing that, and maybe it is all just a coincidence, I am surprised because I have found 3 factors of numbers just today when all the time before I would go days between finding just one. Considering the percentage chance of finding a factor that is on screen when a new P-1 starts, it makes me kinda wonder how I could just have this much "good luck".

You can wonder why you did have so few hit before, too.

Such pattern-seeking is useful when there occasionally are nonrandom factors (e.g., there really is a tiger lurking in those shadows), where there can be a severe penalty for not suspecting nonrandomness and acting on that suspicion, but there are no tigers lurking in factors of Mersenne numbers.

1st composite factor
 
Found my 1st composite factor today:

[Sat Jun 30 05:48:13 2012]
P-1 found a factor in stage #1, B1=555000.
UID: flashjh/P1Main, [URL="http://mersenne-aries.sili.net/exponent.php?exponentdetails=55695851"]M55695851[/URL] has a factor: 5177355259441074001675920029884672048668915182092512593

bits: 181.756[/QUOTE]Nice. Both in stage-1 too.

How do you know how many bits a factor you find is equivalent? I haven't seen that printed on the results anywhere.
