How do you find the number of vertices on a graph?
Use this equation to find the vertices from the number of faces and edges as follows: Add 2 to the number of edges and subtract the number of faces. For example, a cube has 12 edges. Add 2 to get 14, minus the number of faces, 6, to get 8, which is the number of vertices.How many total graphs with 4 vertices?
There are 11 simple graphs on 4 vertices (up to isomorphism). Any such graph has between 0 and 6 edges; this can be used to organise the hunt.Is there a graph with degree 1 1 3 3 3 3 5 6 8 9?
There is no simple graph having a degree sequence (1, 3, 3, 3, 5, 6, 6)- Order of a graph is the number of vertices in the graph. Size of a graph is the number of edges in the graph.
