A299028 Number of vertices in the iterated clique graphs of the 1-skeleton of Plato's icosahedron.
12, 20, 32, 92, 472

Examples
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.
