A simple graph is called regular if every vertex of the graph has the same degree. An n-regular graph is a graph with every vertex with degree n. • The graph of cycle denoted by Cn, for n > 3, consists of n vertices v, v2, ..., vn and edges {v, t}, {v2, v3}, ... {vn-1; 'n} and {v,, v}. • The graph of wheel denoted by W, is obtained when an additional vertex is added to cycle Cn, for n > 3, and connect this new vertex to each of n vertices by new edges. 3.(a) Draw C6, C7, We and W7. 3.(b) Are C, and W, regular graphs? Justify your answer. 3.(c) How many edges and vertices do C6, C7, We and W, have?

Let Vn be the set of connected graphs having n edges, vertex set [n], and exactly one cycle. Form a graph Gn whose vertex set is Vn. Include {gn, hn} as an edge of Gn if and only if gn and hn differ by two edges, i.e. you can obtain one from the other by moving a single edge. Tell us anything you can about the graph Gn. For example, (a) How many vertices does it have? (b) Is it regular (i.e. all vertices the same degree)? (c) Is it connected? (d) What is its diameter?
