Abstract

For each positive integer $n\ge 2$, there is a well-known regular orientable Hamiltonian embedding of $K_{n,n}$, and this generates a regular face 2-colourable triangular embedding of $K_{n,n,n}$. In the case $n\equiv 0$ (mod 8), and only in this case, there is a second regular orientable Hamiltonian embedding of $K_{n,n}$. The current paper presents an analysis of the face 2-colourable triangular embedding of $K_{n,n,n}$ that results from this. The corresponding Latin squares of side $n$ are determined, together with the full automorphism group of the embedding.
