Hm..
thanks for the hint. But in my case maxima get's it input from an formula
editor which represents it's data in openmath and parses it to mathematical
expressions.
This parser produces output like n(n+1). So probalby the problem is exactly
at this point. Or is there a alternative to get openmath into maxima
(directly to the input or its syntax)?
