A db Fig 1 1 In this graph the points a and b are adjacent whereas b and c are non adjacent 2 Let V 1 2 3 4 and X 1 2 1 3 1 4 2 3 2 4 3 4 G V X is a 4 6 graph This graph is represented by the diagram as shown in Fig 1 2 Fig 1 2 In this graph the lines 1 3 and 2 4 intersect in the diagram and their intersection is not a point of the graph Fig 1 3 is another diagram for the graph given in Fig 1 2 Fig 1 3 3 The 10 15 graph given in Fig 1 4 is called a Petersen graph
