Let $k$ be the number of ordered pairs $(i, j)$ of integers such that $1 \leq i \leq 5$, $1 \leq j \leq 5$, and $i + j = 5$. Define $n = 8$. Let $R = k! \cdot S(n, k)$, where $S(n, k)$ denotes the Stirling number of the second kind. Compute the remainder when $34373 \cdot R$ is divided by $75928$.

Let $k = 840$. Let $U$ be the number of ordered pairs $(i,j)$ of integers such that $1 \leq i \leq 23$, $1 \leq j \leq 23$, and $\gcd(i,j) = 1$. Define $S$ as the set of all positive integers $x$ such that $1 \leq x \leq U$, $x$ divides $k$, and $\frac{k}{x} \leq U$. Compute the value of $$ \sum_{n=1}^{|S|} \tau(n), $$...
