I *don't* want it in the x's, though; I want it the e's. I wrote e1=x1+x2+x3 merely to illustrate what I meant by e1. Look back at my original example; I already know that, in three variables, m[4,2,1] corresponds to e3*(e1^2*e2 - 2*e2^2 - e1*e3). I want *that* expansion in general, not the expansion into x's, nor the e[3,2,1,1]+..., which despite being in e's is obviously different from the expansion I refer to. In my noggin I imagine that the algorithm has to go through the e's before it goes into x's. I guess I should look at the code to see. john perry -- You received this message because you are subscribed to the Google Groups "sage-support" group.
