All group‐based latin squares possess near transversals
Authors:Luis Goddyn  Kevin Halasz
Abstract:In a latin square of order n, a near transversal is a collection of n ?1 cells which intersects each row, column, and symbol class at most once. A longstanding conjecture of Brualdi, Ryser, and Stein asserts that every latin square possesses a near transversal. We show that this conjecture is true for every latin square that is main class equivalent to the Cayley table of a finite group.
Keywords:Brualdi's conjecture  Cayley table  complete mapping  latin square  partial transversal
