摘要
提出了复合截集的概念,基于复合截集给出了由元正形置换构造元正形置换的新的递归构造方法,并解决了相应的计数问题。
In this paper,the concept of composite transversal is proposed.Based on this concept,a new recursive construction method of orthomorphic permutations with n+1-variable from one with n-variable is given,and the enumeration problem based on this construction method is solved.
