In this paper, we mainly investigate the class-preserving Coleman automorphisms of finite groups whose Sylow -subgroups are semidihedral. We prove that if is a finite solvable group with semidihedral Sylow -subgroups, then is a -group and therefore satisfies the normalizer property. As some applications of this result, we also investigate the normalizer property of the following groups: the groups whose Sylow -subgroups are semidihedral and Sylow subgroups of odd order are all cyclic, the groups with a nilpotent normal subgroup and a maximal class -group, and the wreath products with a group whose Sylow -subgroups are of maximal class with order and a rational permutation group.

Sylow 2-子群为半二面体的有限群的保类 Coleman 自同构
在本文中,我们主要研究了具有 Sylow 的有限群的保类 Coleman 自同构-子群是半二面体的。我们证明如果是具有半二面体 Sylow 的有限可解群-子群,然后是一个-组,因此满足归一化属性。作为该结果的一些应用,我们还研究了以下组的归一化属性:其 Sylow 的组- 子群是半二面体,奇数阶的 Sylow 子群都是循环的,群和一个幂零正态子群和一个最大的类-组和花环产品和一个团体,其 Sylow- 子组是具有顺序的最大类和一个有理置换群。
