拉丁方

This paper proposes the computer aided method AIC for finding the isotopy classes of latin squares.

本文提出拉丁方合痕分类的计算机辅助方法AIC，该方法结构简洁，复杂度低。

In terms of Latin squares, an isotopy is given by a permutation of rows α, a permutation of columns β, and a permutation on the underlying element set γ.

在拉丁方中，三元组由第α和第β列的一个置换以及其余集合上的一个置换γ给出。

AIC improves the procedure determining if two latin squares are isotopy and reduced the complexity of the procedure by a factor of n !

利用方法AIC，本文对7阶拉丁方作了合痕分类，得到了564个合痕类的代表元。
