Characteristics of a number of gates from the set of all generalized Toffoli gates are studied. Any permutation S is proved to be generated by a n-cycle δ and a permutation τ=i(subscript j, i together. It shows that any neighboring 2-cycle permutation can be generated by at most two NOT gates without ancilla bit.

本文研究了生成Toffoli门集合的可逆逻辑门数的特点，证明了任意置换S可以由n-轮换δ和一个置换τ=i(下标 j，i生成，同时证明了相邻2-轮换可由至多两个NOT门在不增加额外信息位的情况下生成。
