Ooh, this morning greeted me with a new downdriver record. [url=http://factorization.ath.cx/search.php?aq=139314&action=last&fr=&to=]139314[/url]'s downdriver run started with a c131 at index 1724 and ended with a c23 at index 2288 for a total length of 565 lines and a reduction of 108 digits! :toot: Scary [url=http://factorization.ath.cx/aliquot.php?aq=139314]fall[/url], isn't it?

The sequence nabbed the downer a few more times to eventually reach c17 before going back up to its current status as a majestic c95=2^2*7^2*c at index 2866 (it's had the 2^2*7 for 513 lines... go away! :flex:).

As a tip: don't post status updates when the guide is likely to change quickly. This will almost certainly change within the next 10 lines.

100436: finally finished the 129-digit GNFS of line 1754:

Sun May 10 17:46:02 2009 prp63 factor: 209431713174846009624018770436135134928395257658939146425157043
Sun May 10 17:46:02 2009 prp66 factor: 544822173215582165559955858693114639267710218173715482852040500613

It still has the 2^4*31 driver in line 1755.

130396 just acquired the downdriver for the third time, this time at the lower height of 91 digits. *hopes this one's a long one*

Just finished my biggest gnfs yet on a c138 from 184416. Unfortunately all it got me was an extra 5 factor on the next line...

And the line after that looks to be another hard c138. If it passes ecm I might be giving up on this sequence. Currently 2^3*3*5^2 at 140 digits. :surrender

escape from 2^4*31?

Edit: Cofactor is a c125 which seems to need GNFS.
