## Summary

In graph theory, the corona product of graphs $G$ and $H$, denoted $G \circ H$, can be obtained by taking one copy of $G$, called the center graph, and a number of copies of $H$ equal to the order of $G$. Then, each copy of $H$ is assigned a vertex in $G$, and that one vertex is attached to each vertex in its corresponding $H$ copy by an edge.
