Consider the following graph: 1.) There are n vertices labeled 1...n. 2.) There exists an edge between vertices u and v iff label(u) | label(v) (the label of u divides the label of v). How many unique simple cycles does such a graph with n vertices contain? Note(s): The exact function in terms of n may be too hard to get (lol), but growth orders are also acceptable, with appropriate proof. The graphs are non-directed graphs... no double-edges are allowed, but self loops are present. Cycles may be counted one way or both ways (that is, if 1-2-4-1 is counted as a cycle, then 1-4-2-1 may or may not be counted, as long as you make your counting method explicit).
