Comment #5 on issue 3128 by [email protected]: Sum and Product
manipulations
http://code.google.com/p/sympy/issues/detail?id=3128
Change of index means making a substitution on the index variable, like n
-> n + 1. Reordering means changing something like Sum(expr, (i, 1, n), (j,
1, m)) to Sum(expr, (j, 1, m), (i, 1, n)), which is more complicated if n
is replaced with something that depends on j.
