That is a nice escape, straight from 2^4 * 31 to the downdriver!

I'll add it to the list.....barring an extremely lucky strike for someone else, this is the last for 2011!

Party like it's 2012...

 2011-12-31, 03:24 #258 schickel     "Frank <^>" Dec 2004 CDP Janesville 2×1,061 Posts Updated....and a size check on the post shows that we're good to go: we can get (almost) as many terminations/merges in 2012 as are in the top post now and still fit them all into one post....

Yep, I just found 241506 last night:
241506.2822 merges with 4800.7

I noticed 816792 a couple weeks ago also (it should actually be credited to 2011). I didn't say anything at the time and then I couldn't remember which sequence it was so I just figured it would turn up eventually. Which it has. I assume Greebley found the merge, but his last post was Oct. 19th.

I assume that when you say "I found..." you mean your workers turned it up, correct?

That's interesting, becuase on 12/14 I had posted some excerpts from the overall status in the updates thread and included this line:
Code:
816792  1186. sz 118 2 * 5 * 53
So I had caught it just after it started its first plunge down the downdriver slope.....

Yes, in true capitalist style I don't do anything myself, my workers do it all for me. I've had much more success in terminations by following the workers' simple rules than by trying to pick winners myself... I'm sure there's some life lesson in there but I don't seem to be learning it.
