Dieter, Here are some simple results (like the examples in your post below), on a machine with 32GB of memory.

I need to learn how to do 'for n=1 to m .. next n' (or for n=0 to m.....next n) loops that are child's play in BASIC or Assembly, etc languages. But I am 'academically' interested what brute force would do with big modern gaming machines with lots and lots of amazing RAM. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
