Comment #18 on issue 3128 by asmeu...@gmail.com: Sum and Product manipulations http://code.google.com/p/sympy/issues/detail?id=3128 I am sure that mathematica can represent unevaluated summations. Anyway, reordering the limits where we have to change them to get the same answer is somethi

Comment #17 on issue 3128 by thilina@gmail.com: Sum and Product manipulations http://code.google.com/p/sympy/issues/detail?id=3128 What does reverse order of limits mean? Is it converting Sum(x, (x, 1, 10) --> Sum(x, (x, 10, 1))? If so, would an interface like reverse_order(Sum, index1, i
