- N. J. A. Sloane, Triakis icosahedron showing distances from a trivalent vertex. The base vertex is labeled 0, and the vertices at distances 1, 2, and 4 are marked, as are some vertices at distance 3. Unlabeled vertices should also be labeled 3. [This image was constructed by adding labels to an image on the Wikipedia page.]
