On finding the non-isomorphism classes of the (n x n)/k semi-latin squares


P E CHIGBU

Abstract




We give and prove group-theoretic lemmas which would enable one to find the non-isomorphism classes of the (n × n) / k semi-Latin squares. These lemmas are most useful when the sizes and number of semi-Latin squares under consideration are large, and the computing method via the ‘nauty package' for finding their isomorphism classes, given by Bailey and Chigbu, is not readily available.
