On exact products of two dihedral groups

Kan Hu, Hao Yu

An exact product of two finite groups $H$ and $K$ is a finite group $X$ which contains $H$ and $K$ as subgroups, satisfying $X = H K$ and $H \cap K = {1_{X}}$ . In this paper, we provide…

The Product of a Semi Dihedral Group And a Cyclic Group

Hao Yu

Let $X (G) = GC$ be a group, where $G$ is a semi dihedral group and $C$ is a cyclic group such that $G \cap C = 1$ . In this paper, $X (G)$ will be characterized.
