The toroidal $n$-queens problem asks the same question where the board is considered on the surface of the torus and was asked by P\'{o}lya in 1918. Let $Q(n)$ denote the number of $n$-queens configurations on the classical board and $T(n)$ the number of toroidal $n$-queens configurations. P\'{o}lya showed that $T(n)>0$ if and only if $n…
