   • 2015, Sean Eberhard, Freddie Manners, Rudi Mrazović, “Additive triples of bijections, or the toroidal semiqueens problem”, in arXiv‎:

     This problem is equivalent to counting the number of orthomorphisms or complete mappings of ${\displaystyle \mathrm {Z} /n}$}, to counting the number of arrangements of ${\displaystyle n}$ mutually nonattacking semiqueens on an ${\displaystyle n\times n}$ toroidal chessboard, and to counting the number of transversals in a cyclic Latin square.
