Sorry for the late reply and confusion with this number, I already queued this number on my machine, see post 256, ETA is 38 hours. I should have put a reply that I was going to do it after that post.

Reserving 2617_71_minus1 if it is available. Thanks.

Reserving GW_3_515

RichD 2015-08-06 14:04

GW_3_513 killed.

GC_8_264 a little over two days remain in LA.

RichD 2015-08-08 20:14

GC_8_264 factors were reported to FDB before I finished up.

[QUOTE=RichD;407494]GC_8_264 factors were reported to FDB before I finished up.[/QUOTE]

That's weird. You were the only one that reserve this number.

RichD 2015-08-08 21:14

It wasn't factored before I started because info was missing.

If you look at the .fb & .poly files, the R0/R1/Y0/Y1 values are missing.

I double checked in FDB before computing the needed values.
