Let $p$ range over the positive integers. Define $\alpha = 1$ if there exists a positive integer $q$ such that $pq = 72$, $\gcd(p, q) = 1$, and $p < q$; otherwise, $\alpha = 0$. Let $\beta$ be the number of such $p$ for which this condition holds. Let $S$ be the set of all ordered pairs $(x, y)$ of positive integers su...
