I'll run from 100k.

Two days on the C152 got me nothing better than 1.58e-12. I yield to wombatman's poly.

HP[SUB]6[/SUB](96) has a c168. I ran a full t55 on it.

If any of you feel like looking for a poly you should go ahead.

But I have a few numbers waiting for GNFS, so it might be a while before I get to it.

Here's a quick initial one:

Aliquot Sequence 3366 is now ready for GNFS with a c154.

The last term is [url="http://factordb.com/sequences.php?se=1&aq=3366&action=range&fr=2120&to=2120"]here[/url].

The composite is:

A nice poly is requested.

Starting at 100,000 and running overnight.

A little low, but a good start.
