Latin squares and critical sets of minimal size

IsotoIHsl:n that lower bounds for infinite N of order n. hand or computer, strong critical sets of minimum nOn-lS01110Tnitnc reduced latin squares of order less than or of order 6. These latin squares have been taken from 129 onwards. We summarise our results in Table the numbering system listed by Denes and Keedwell latin squares. This numbering system is based on the ,<:n,,-r1i',rrHl1<:rn classes of the latin squares and in detail on pages 128 114 and 129 of [3]. These numbers are listed as the class and are given in column two of Table 1. of critical sets of minimum cardinality for each latin square are in the Appendix.
