That's not obviously the same as the result I specified. I left out that I know the number of variables I have available; in the example above, I have three variables, so I'm looking specifically for e1=x1+x2+x3, etc. I don't see how I get that from the expression e[3,2,1,1] - 2*e[3,2,2] ... I'm quite new to this topic, hence my lack of clarity. Sorry about this. john perry > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
