The Robertson-Wegner graph is of the four -cage graphs, also called Robertson's cage (Read and Wilson 1998, p. 273). Like the other -cages, the Robertson-Wegner graph has 30 nodes. It has 75 edges, girth 5, diameter 3, and chromatic number 4. The Robertson-Wegner graph has automorphism group order 20.
It has LCF notation signature and is illustrated above in its two order-5 LCF embeddings.
