Yes, it's a typo. I've corrected it.

[quote=schickel;172483][code]738912 Mini-Geek 24 Dec 2009 100 2025 Merge with 86616[/code][/quote]
:cool: My first termination large enough to be noted in this thread...even if it's just a merge. I've put it here and in the Subproject page...is that right? After all, I've had it reserved for both sections, even if it peaked at 100 where I moved it.

Batalov 2009-12-24 07:55

Congrats, nice one! Over a 100 is very good.

Here's another one Wieb missed.....
 
I was looking around in Wieb's range at some of the longer ones and found this merge for 254490:[quote=factordb.com]

1 Merge:
[B]Merge at n=2642 with 249372, n=10[/B][/quote](Unknown date, but sometime before the "last update" for the table, which was 10 Oct 2008....and a peak of 89 digits at line 846)

That's a nice Christmas present! :smile:

Nice. Are you going to check the others too?

I think that Wieb's next update may be coming soon, he tends to do them about once every 6 months. Have you tried to contact him again? It may now be important to do so because he will probably waste loads of time duplicating Subproject 2 otherwise.

[/QUOTE]Funny you should mention that....[quote=factordb]2 Merges:

I'm hoping someone with academic contacts can get in touch with him or someone who knows him and get him hooked in....[quote=10metreh]It may now be important to do so because he will probably waste loads of time duplicating Subproject 2 otherwise.[/quote]Let's hope not, since those cycles could be put to some other use.... We need something someone could write a paper about.....
