[QUOTE=Shiva;171716]For some reason, I've always been interested in the sequence described at [URL="http://www.research.att.com/%7Enjas/sequences/A031439"]http://www.research.att.com/~njas/sequences/A031439[/URL][/QUOTE]

Just for kicks I put the next one in the database: [URL="http://factorization.ath.cx/search.php?query=449841219907460920775318695544750644551839056457610390058425898135489775905100041988620898230138432211897028854862570700651374293486007705678606149903472725394769924910445995213560566679330414698317499229057^2%2B1"]A031439(24)[/URL].

I'm running a few curves on my PC at B1 = 3M right now. It's highly unlikely to go anywhere, of course.

AM is Alexis Michon

I don't remember doing any work on this number, it is possible, but that might not be me.

Could it be Jesper Gerved?

Aliquot problem
 

Never mind....Andi47 beat me about the error message. I think it was my upload that blew up the sequence.

[QUOTE=kar_bon;171634]and i've inserted

ECM, 5500 curves, B1=11M, B2=?, Alex Kruppa, Paul Leyland
ECM, 9000 curves, B1=44M, B2=?, Alex Kruppa, Paul Leyland

(Note: B2-values are not available, so i inserted dummys)

from [url]http://www.worldofnumbers.com/topic1.htm[/url]
from 2004, so it's time to break this C204![/QUOTE]I've started running a few curves at B1=11e7. It shouldn't take too long to complete a t55 as fewer than 5000 curves are needed.

Unfortunately, this number is still very hard by GNFS. Not impossible with today's technology, but decidedly non-trivial.

Not sure if its worthwhile bringing this up again, but when I view the aliquot sequence 230160 I get a different error this time than previously. The new error is
[code]
Id 31989820 not found
Sequence ended:
Show graph


Warning: array_slice() expects parameter 1 to be array, null given in /var/www/search.php on line 531

Warning: Invalid argument supplied for foreach() in /var/www/search.php on line 533
[/code]

The previous error still allowed me to see at least some of the lines which were submitted.

Looks like there are some inconsistencies in the database. I'll look after this one.

I notice there is one person who is keeping his c375 on to of the queue for 3 days already. I don't even get the chance to run a few 250K curves.

I suggest disabling the 3M curves to prevent using the system in this way.

or disable "ecm very high limits" for anything bigger than c250 (or even c200).
