Factcomb

Function: factcomb (<expr>) Tries to combine the coefficients of factorials in <expr> with the factorials themselves by converting, for example, (n + 1)*n! into (n + 1)!.

factcomb(3/(x+y)^2 - 4/(x-y)^2 + 5/(x^2-y^2));

sumsplitfact if set to false will cause minfactorial to be applied after a factcomb.

(%o1)                                true
(%i2)
