Minfactorial

Function: minfactorial (<expr>) Examines <expr> for occurrences of two factorials which differ by an integer. minfactorial then turns one into a polynomial times the other.

T:binomial(2*n,n)*(42*n+5)/(2^(12*n+4));
minfactorial(ratsimp(subst(n+1,n,T)/T));

          (%i1) n!/(n+2)!;
                                         n!
          (%o1)                       --------
                                      (n + 2)!
          (%i2) minfactorial (%);
                                          1
          (%o2)                    ---------------
                                   (n + 1) (n + 2)

(%o1)                                true
(%i2)
