If the vertices on the top face of a cube are labelled as ABCD clockwise, and the corresponding vertices on the bottom face are labelled EFGH. Note that A and G are diagonally opposite on the cube. See image of cube below.
We want to consider the possible routes along the edges of the cube from one vertex to another. A trail is a route that does not repeat any edge, but it may repeat vertices. For example, ABFE and ABCDAE are trails, but ABCB isn’t a trial. The number of edges covered in a trail is called its length.
a. Determine how many trails there are of length 3 in the cube. Here a trail between two vertices is regarded as the same in either direction.
