[QUOTE=R.D. Silverman;85995]Is anyone but P. Ochem and me working on these?

I predicted that people would pick off the low hanging fruit then give up.......[/QUOTE]


I'm still working on these with an old machine.

[QUOTE=bhebden;86012]I'm still working on these with an old machine.[/QUOTE]

What machine? I got my last two results on a single, 6 year old
1.5GHz Pentium IV running SNFS. It is doing 6,5,199- now and will then
do 6,5,199+.

Progress *can* be made on these numbers with limited resources. I was
just wondering if anyone else was working on them.

Your help is appreciated. Have you had any result luck?

em99010pepe PM-ed me a couple of times about setting up NFS on these numbers.

To my shame, I've been so swamped in Real Life (tm) that I've only been able to give him the bare minimum of information :redface:

Something that hasn't helped me is that he's running under Windows and almost all my experience these days is with various flavours of Unix. I know that you're primarily Windows-based at present. Perhaps you could PM em99010pepe to provide encouragement and practical assistance and advice.

Maybe old isn't the right term. How about ancient?
It's a dual Celeron 533MHz (PII era) with 256M memory running Linux.

I've been picking at numbers with ecm but just managed to get ggnfs working on it. After a little testing, I'll pick a number to tackle.

6,5,199-
