Noun

 * 1) * {{quote-journal|en|year=2015|date=|author=Sean Eberhard; Freddie Manners; Rudi Mrazović|title=Additive triples of bijections, or the toroidal semiqueens problem|journal=arXiv|url=http://arxiv.org/abs/1510.05987|doi=|volume=|issue=|pages=
 * passage=This problem is equivalent to counting the number of orthomorphisms or complete mappings of $$\Zeta/n$$}, to counting the number of arrangements of $$n$$ mutually nonattacking semiqueens on an $$n\times n$$ toroidal chessboard, and to counting the number of transversals in a cyclic Latin square. }}
