WebA trivalent graph of girth 1 7 . Geoffrey Exoo Department of Mathematics and Computer Science Indiana State University Terre Haute, IN 47809 [email protected] Abstract A family of trivalent graphs is described that includes most of the known trivalent cages. A new graph in this family is the smallest trivalent graph of girth 17 yet discovered. WebOct 6, 2002 · The θr-girth of a graph G is the minimum number of edges of a subgraph of G that can be contracted to θr. This notion generalizes the usual concept of girth which corresponds to the case r=2. In ...

WebThe example of determining the girth of a graph is described as follows: In the above graph, the Girth is 4. This is because, from the above graph, we can derive three shortest cycles, i.e., 1-3-6-4-1 or 4-6-7-5-4-1 or 1-2-5-4-1, and the shortest cycle has 4 numbers of edges. So the Girth of this graph will be 4. Webgraph, and joining three consecutive vertices of the cycle to all vertices in the complete graph. The radius is half the length of the cycle. This graph was ... graph, i.e., a graph of diameter d and girth 2d+1 for some d ≥ 1. For example, Moore graphs include the complete graphs, the odd cycles, the Petersen graph ... mヨドバシ

Websimple connected unicyclic graphs G, where jV(G)j 6 and jE(G)j 8. In doing so, we provide further evidence that Grossman’s conjecture is true. Lemma 1. Let G be a connected unicyclic graph of odd girth and jV(G)j 4. Then, 2 jV (G)j 1 R(G;G). Proof. This follows from Theorem B. Notation. Let C. k 1. Hbe the graph obtained by identifying a ... WebA graph @C is symmetric if its automorphism group acts transitively on the arcs of @C, and s-regular if its automorphism group acts regularly on the set of s-arcs of @C. Tutte [W.T.

A graph is defined as set of points known as ‘Vertices’ and line joining these points is known as ‘Edges’. It is a set consisting of where ‘V’ is vertices and ‘E’ is edge.
