...or simply run factMsieve.pl and the first thing it will say will be:

[FONT=Arial Narrow]"Error: evaluated polynomial value 8209836131236623540106248032442393614982637631141339598467747244677911494877848116936777629774248859738700738214196985237506543807286694994580847683477459 is not a multiple of n!"[/FONT] :-)

So did I get this right -- that the excercise is to factor a number which is already factored? It's different strokes for different folks, but I'd say (my) life is too short for that. Why not some other C154? There's surely enough for everyone...

[SIZE=1]Siew's E score is better, though. It is 2.805e-12[/SIZE]

The people at the moment time interest this number. And it in the desires is not lonely. It is a lot of interested persons.

[/code]You should play around with all six of these. Hint: larger.

You will probably be able to pool your existing relations with any new ones you find, so don't throw out what you have so far.[/quote]

Yes good then will be a little if I lay out this key in an open kind.
And for whom it is necessary. I think that can make.

Why is the Result not in the DB? :pals:

Allow to take an interest, whether you from what know these keys???
If yes then it becomes clear why the result is not published.

Hi, i am german and living in Bremen.
Don`t know something about this Number - but i think it maybe a Number from Nagracards for Sat-TV?
I have read something Years ago about searching the Key for Nagra Cards.

If it is so keys already would be in a network! Though it is necessary to tell Germany is the country which them has created.

tanx a lot.
seems someone knows something about source of this key...

i know only these N number, although.

Previousle i made some keys with similar lengths but it was fast and clear...

That my first key with such lo yield.

If this number was already factored by someone, then i will tell my friends to not disturb me with that. Think better to search more in www to find precomputed keys.
I have more important tasks now :-)

i thought that low yield caused by my build of gnfs binaries...
