It might not seem like the most logical path to homeownership — or at least not the first place you’d think to look for properties. But the U.S.An Euler circuit is a circuit that uses every edge in a graph with no repeats. Being a circuit, it must start and end at the same vertex. Example. The graph below has several possible Euler circuits. Here’s a couple, starting and ending at vertex A: ADEACEFCBA and AECABCFEDA. The second is shown in arrows. Multiplying by the two possible orientations, we get $264$ oriented Eulerian circuits. If we know which node is the first, but not which edge is the first, we can also start with two possible edges out of that node, getting $528$ oriented Eulerian paths starting at that node ($2640$ oriented Eulerian paths total).The graph does have an Euler path, but not an Euler circuit. There are exactly two vertices with odd degree. The path starts at one and ends at the other. The graph is planar. Even though as it is drawn edges cross, it is easy to redraw it without edges crossing. The graph is not bipartite (there is an odd cycle), nor complete.

Euler’s Path: d-c-a-b-d-e. Euler Circuits . If an Euler's path if the beginning and ending vertices are the same, the path is termed an Euler's circuit. Example: Euler’s Path: a-b-c-d-a-g-f-e-c-a. Since the starting and ending vertex is the same in the euler’s path, then it can be termed as euler’s circuit. Euler Circuit’s Theorem
