I am looking for $n$, where
$$\dfrac{2^{-3 n-2} \pi ^{n+1}}{(n+1)!}<\dfrac{1}{10000000000000000}$$
We can just test values of $n$ and find the smallest $n = 13$, or any $n \gt 13$ or can use various other approaches/commands to fnd this result.
When I try
Reduce[152587890625*2^(14 + 3*n)*Pi^(1 + n)*(1 + n)! < 64^n*(1 + n)!^2, n, Integers]
Mathematica fails to find an answer.
However, when I direct the call to WA, I get
Why is Reduce not finding this using MMA, V13.0.1, x86, Windows 10, but WA shows the result?
