Hi,
A few days ago I submitted to Anthony Forbes a 597-digit 6-tuplet and had it verified as a new world record:

http://anthony.d.forbes.googlepages.com/ktuplets.htm

This number is only a few digits above the previous record, and it should be quite possible for the superblock project to beat it!

The program used was based on the b14 version of dga's xptminer (which was the latest version I was able to compile using Windows and Visual Studio) and ran on 11 cores for about a month before it suddenly surprised me with a find. I'll give some further details later.

The 6-tuplet is

Awesome! Congratulations - and thanks for doing it. Note that I fixed a bug in the b15 version that was breaking things under windows (so it's now called b16) so you might have an easier time getting it running on VS now.
