Sorry! On mklasson's site (the person who tracks these factors), that is the notation used. The intended number is 13*2^792-1. By this time, I should know better.

Thank you.

Taking C196_5889307277311_17m1_c

ETA morning of Monday 6 March

I'll take 137^62+62^137 next.

Reserving C170_11040_10011.

Approximately how much memory would be needed to post-process C171_829332_3638 with 250M relations?

It will fit very happily in 12 or 16GB, it might be a bit of a squeeze in 8GB but would probably work if you're not doing anything else on the machine.

Thanks! I have 8GB on my i7 so I could give it a try if folks don't mind possibly giving me a little coaching.

I'm pretty sure it'll fit in 8GB, and I'll try to answer any questions you have. I'll also be happy to run it in case it proves too big for your machine.

That's a 32-bit job. Won't it need more that 250M relations? Maybe not 470M but in the mid 300s at least?

I've done 32-bit jobs from the 14e queue with a similar setup to you and they worked out ok. Might take a lot of time to complete LA but it is satisfying.

I estimated the number of relations from the number of initial work units, so it will be higher.

And thanks for the offer of help, Mike!
