Ok, thanks.

I don't understand, why this would be hard?  The product of 3 (or more)
expressions is already represented as a sequence in the "mul" expression
type, so couldn't ginac just find all subexpressions in the product of type
exp, and then collect them?  I guess I don't know how these auto-simplify
methods are implemented.

Anyway I will try the subs/wildcard method as you suggested, I didn't think
of that.  Thanks again!
