An antelope graph (Jelliss 2019) is a graph formed by all possible moves of a hypothetical chess piece called an "antelope" which moves analogously to a knight except that it is restricted to moves that change by three squares along one axis of the board and four squares along the other. To form the graph, each chessboard square is considered a vertex, and vertices connected by allowable antelope moves are considered edges. It is therefore a -leaper graph.
The plots above show the graphs corresponding to antelope graph on chessboards for to 7.
The antelope graph is connected for , Hamiltonian for (trivially) and 14 (but for no odd or other even values ), and traceable for and 21 (with the status for unknown and unknown).
Precomputed properties of antelope graphs are implemented in the Wolfram Language as GraphData["Antelope", m, n].
