数字阵列转化的讨论

Discussion about transformations of numeric arrays

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 binoups, arrays from two classes can not transfom to each other, arrays in a same class can transfonn to each other. Put forward an algorithm for transforming any numeric array to the standard array.
