A walk in a graph in which no vertex is repeated is the definition for a path (Graphs and Digraphs 5th edition; Zhang, Chartrand, Lesniak). Since the example you have shown has a vertex repeated, it is no longer a path. A cycle is not a path by itself (while it is a walk, more specifically a closed walk ).

In graph theory, a cycle graph or circular graph is a graph that consists of a single cycle, or in other words, some number of vertices (at least 3, if the graph is simple) connected in a closed chain. The cycle graph with n vertices is called Cn. The number of vertices in Cn equals the number of edges, and every vertex has degree 2; that is, every vertex has exactly two edges incident with it.
