If graphs are allowed to have an infinite number of vertices and edges. then Lemma 10.4.1 is false. Give a counterexample that shows this. In other words. give an example of an “infinite tree” (a connected. circuit-free graph with an infinite number of vertices and edges) that has no vertex of degree 1.
