Klein Graphs
In the mathematics, mathematical field of graph theory, the Klein graphs are two different but related regular graphs, each with 84 edges. Each can be embedded in the orientable Surface (topology), surface of Surface (topology)#Classification_of_closed_surfaces, genus 3, in which they form dual graphs. The cubic Klein graph This is a 3-regular graph, regular (Cubic graph, cubic) graph with 56 vertices and 84 edges, named after Felix Klein. It is Hamiltonian graph, Hamiltonian, has chromatic number 3, chromatic index 3, radius 6, diameter 6 and girth (graph theory), girth 7. It is also a 3-k-vertex-connected graph, vertex-connected and a 3-k-edge-connected graph, edge-connected graph. It has book thickness 3 and queue number 2. It can be embedded in the Manifold#Genus_and_the_Euler_characteristic, genus-3 orientable Manifold, surface (which can be represented as the Klein quartic), where it forms the Klein map with 24 heptagonal faces, Schläfli symbol 8.
