Let $X$ be an orientable hyperbolic surface of genus $g\geq 2$ with a marked point $o$, and let $Γ$ be an orientable hyperbolic surface group isomorphic to $π_{1}(X,o)$. Consider the space $\text{Hom}(Γ,S_{n})$ which corresponds to $n$-sheeted covers of $X$ with labeled fiber. Given $γ\inΓ$ and a uniformly random $φ\in\text{Hom}(Γ,S_{n})$, what is the expected number of fixed points of $φ(γ)$? Formally, let $F_{n}(γ)$ denote the number of fixed points of $φ(γ)$ for a uniformly random $φ\in\text{Hom}(Γ,S_{n})$. We think of $F_{n}(γ)$ as a random variable on the space $\text{Hom}(Γ,S_{n})$. We show that an arbitrary fixed number of products of the variables $F_{n}(γ)$ are asymptotically independent as $n\to\infty$ when there are no obvious obstructions. We also determine the limiting distribution of such products. Additionally, we examine short cycle statistics in random permutations of the form $φ(γ)$ for a uniformly random $φ\in\text{Hom}(Γ,S_{n})$. We show a similar asymptotic independence result and determine the limiting distribution.
