Graph Theory: 49. Cartesian Product of Graphs

What is the Cartesian product of two graphs? We start with a reminder of what this means just for sets and then provide the formal definition for graphs. We include a few examples to become familiar with the idea and we also briefly discuss what a hypercube (or n-cube) is in graph theory. -- Bits of Graph Theory by Dr. Sarada Herke.
