In the mathematical field of graph theory, the Clebsch graph is either of two complementary graphs on 16 vertices, a 5-regular graph with 40 edges and a 10-regular graph with 80 edges. endstream The number of connected simple cubic graphs on 4, 6, 8, 10, ... vertices is 1, 2, … A regular graph with vertices of degree is called a ‑regular graph or regular graph of degree . x�3�357 �r/ �R��R)@���\N! �Fz`�����e@��B�zC��,��BC�2�1!�����!�N��� �1Wp�W� Since degree of every vertices is 4, therefore sum of the degree of all vertices can be written as N × 4. <> stream Regular Graph: A graph is called regular graph if degree of each vertex is equal.
