Man, I guess I need to get different sequences.....Clifford just emailed me about another termination.

This time he reports that 930306 bites the dust (although it looks like he hasn't uploaded yet....)

Clifford strikes again!
 
Just got this via email:[quote=Clifford]Yesterday I began working on 659160 which Forum members
had extended to 1506. 2^2 * 3 * c104 sz 105. ECM found a
27-digit factor for the c104, and things were off and running.
After reaching a maximum of 106 digits, it merged this morning
with 44988:

659160:i2307 = 44988:i20 = 305864[/quote]So scratch another one!

752976 terminates (I suppose 'merge with 470794', but it's then only 33 steps from completing)

[QUOTE=schickel;263335]Just did a complete status update for the first post. Unfortunately, just one active downdriver showing this time. :sad:[/QUOTE]
