WebThe lengthof a face F in a plane graph G is the total number of edges in the closed walks in G that bound the face. Proposition 2 If l(Fi) denotes the length (the number of edges in its boundary), of face Fi in a plane graph G, then 2e(G) = Xl(F i). Definition 7 A bond of a graph G is a minimal non-empty edge cut. Proposition 3 WebSection 4.2 Planar Graphs ¶ Investigate! 30. When a connected graph can be drawn without any edges crossing, it is called planar. When a planar graph is drawn in this way, it divides the plane into regions called faces. Draw, if possible, two different planar graphs with the same number of vertices, edges, and faces.

We explore the correspondence of magic labelings of graphs with magic squares and define polytopes of magic labelings to give a description of the faces of the Birkhoff polytope as polytopes of magic labelings of digraphs.",
