利用置换群将阵列分为两个等价类,两类阵列之间不能互化,同类阵列间可以互化,给出了将任意阵列移成标准阵列的算法.

Classify all numeric arrays into two equivalent classes by using permutation groups, arrays from two classes can not transform to each other, arrays in a same class can transform to each other. Put forward an algorithm for transforming any numeric array to the standard array.
