[QUOTE=RichD;513173]You are correct [B]VBCurtis[/B]. I was going to ask [B]richs[/B] if he wanted to do 256128979_23m1 instead and I would take over this number and perform some low level sieving after I got back in town next week. One or both of the "lim"s should have been increased in hindsight. My fault.[/QUOTE]
I'll do a little experimenting with very low Q and the f siever. PM me when you're back in town, hopefully I'll have a couple million relations for you as a head start on finishing it up.

As suggested by Rich and Sean, I will drop 4784213763211_17m1. It appears on the cusp of making a matrix.

Taking 256128979_23m1.
