Let $n = 9$. Let $S$ be the set of all positive integers $k$ such that $1 \le k \le 90$ and $20$ divides $F_k$, where $F_k$ denotes the $k$-th Fibonacci number. Let $k = \sum_{i=1}^{|S|} \varphi(i) \left\lfloor \frac{3}{i} \right\rfloor$, where $\varphi$ is Euler's totient function. Compute $\binom{n}{k} \cdot !(n - k)...
