Lets define Graph G as a graph with "n" vortexes and no edges. Define C(G) as a number of cycles that starts from a point, visit all points exactly once, and comes back to the point that they started (The paths made can't cross each other). Define R(G) as a number of routes that starts from a point, visit all points exactly once, and finishes at another point. (The paths made cannot cross each other.) Show that R(G)≥n*C(G). Also, show the reason why is it inequality instead of an equation, and show the equrilibrum conditions.
