%H N. J. A. Sloane, <a href="/A329772/a329772.pdf">Triakis icosahedron showing distances from a 10-valent vertex</a>. The base vertex is labeled 0, and the vertices at distances 1 and 3 are marked. The 15 unlabeled vertices should have the label 2. [This image was constructed by adding labels to an image on the Wikipedia page.]
