The house X-graph, also called the full house graph, is the house graph plus the two edges connecting diagonally opposite vertices of the square base, illustrated
above. It is also one of the two graphs obtained by removing two edges from the pentatope graph (the other being the
wheel graph). It is implemented
in the Wolfram Language as GraphData["HouseXGraph"].
