I have the following function in Mathematica:
$\frac{x! \sum _{i=1}^j (-i+j+1) S_{j+1}^{(-i+j+2)} x^{-i+j+1}}{(x-j)! \left((1-x)_j\right){}^2}$
Defined as:
a[n_, m_] := (n - m)*StirlingS1[n + 1, n + 1 - m]
p[x_, j_] := Sum[a[j, i - 1]*x^(j - i + 1), {i, 1, j}]
m[x_, j_] := (Factorial[x]/
Factorial[x - j])*(p[x, j])/(Product[(x - i)^2, {i, 1, j}])
When I try to compute the limit of m[x, j]/j
when $x$ approaches infinity, it takes too long to provide a solution:
Limit[m[x, j]/j, x -> Infinity]
How can I get the solution of this limit in a reasonable amount of time?
