Math Problem Statement
It seems there was an issue generating the image. Let me describe how you can manually draw the multigraph based on the degrees { 1 , 1 , 4 , 5 , 6 , 7 } {1,1,4,5,6,7}.
Steps to draw the multigraph: Vertices: Draw 6 vertices, label them from π 1 V 1 β to π 6 V 6 β , and assign the following degrees:
π 1 V 1 β and π 2 V 2 β each with degree 1. π 3 V 3 β with degree 4. π 4 V 4 β with degree 5. π 5 V 5 β with degree 6. π 6 V 6 β with degree 7. Edges: Start connecting the vertices:
Connect π 1 V 1 β and π 6 V 6 β with 1 edge. Connect π 2 V 2 β and π 5 V 5 β with 1 edge. Connect π 3 V 3 β , π 4 V 4 β , π 5 V 5 β , and π 6 V 6 β using multiple edges and loops: For example, π 6 V 6 β can have several edges connected to π 4 V 4 β , and a loop (edge connecting π 6 V 6 β to itself) can be used to fulfill the degree requirement of 7. Loops and Multiple Edges: Since it's a multigraph, use additional edges between vertices or loops to meet the degree conditions where necessary.
