关于k阶错排问题

On the Problem of the Derangement of Order k (1≤k≤[1/2(n-1)]) of n Order Elements

本文给出k阶错排的定义,并建立起k阶错排的几个计数公式和生成方法.

In this paper, the concept of the derangement of order k (1≤k≤ ?) of n order elements will be given and some counting formulae and generating-method will also be established.
