As an addendum to my previous response: Let me suggest that you look at the thread <http://mathforum.org/epigone/sci.math.symbolic/glersnerdwand>. The basic matter being addressed is the same, although Maple was the CAS involved. By the way, I'll also be interested in answers to your second question.
