 A299030 Number of vertices in the iterated clique graphs of the 1-skeleton of Plato's octahedron. 1
 6, 8, 16, 256 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,1 COMMENTS The octahedron was the first known example of a k-divergent graph. LINKS Miguel A. Pizaña, The icosahedron is clique divergent, Discrete Mathematics, 262 (Feb. 2003), pp. 229-239. EXAMPLE By definition, the zeroth iterated clique graph of a graph G is equal to G itself; since the octahedron has 6 vertices, a(0)=6. The first iterated clique graph of the octahedron has 8 vertices; hence, a(1)=8. PROG (YAGS) K:=CliqueGraph;; g:=Octahedron;; kg:=K(g);; Order(kg); # It outputs the number of vertices in the first iterated # clique graph of the octahedron. CROSSREFS Cf. A299028, A063723, A053016.
