Icosian game

Definition

The Icosian game is a mathematical puzzle that involves finding a Hamiltonian path on a specific graph, which represents the vertices and edges of a dodecahedron. This game was created by the mathematician William Rowan Hamilton in the 19th century, and it serves as a way to explore Hamiltonian cycles and paths through a graph. The primary goal of the game is to determine if there is a way to visit every vertex exactly once before returning to the starting point.
