 A299028 Number of vertices in the iterated clique graphs of the 1-skeleton of Plato's icosahedron. 1
 12, 20, 32, 92, 472 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,1 COMMENTS It is known that the sequence of orders of the iterated clique graphs of the icosahedron goes to infinity. 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 icosahedron has 12 vertices, a(0)=12. The first iterated clique graph of the icosahedron has 20 vertices; hence, a(1)=20. PROG (YAGS) K:=CliqueGraph;; g:=Icosahedron;; kg:=K(g);; Order(kg); # It outputs the number of vertices in the first iterated # clique graph of the icosahedron. CROSSREFS Cf.
