Abstract: This talk will use techniques from linear algebra and elementary group theory to count several different combinatorial structures that have come up in recreational mathematics.

For example, the number of certain subgraphs of a family of grid graphs can be shown to satisfy a linear recurrence using the Cayley–Hamilton theorem, and the number of subsets of $\{n, n+1, n+2, \hdots, n+m\}$ such that the product is a perfect square can be shown to be of the form $2^N$ by using properties of matrices over the field of two elements.
