摘要
In this paper we investigate the Bruhat order on the class of Latin squares. We study its cover relation and minimal elements. We prove that the class of Latin squares of order n, with n is not an element of {1, 2, 4}, has at least two minimal elements, and we present a process to construct some minimal Latin squares for this relation.
