Dihedralizing the quaternions

Abstract
In this paper, we take the classic dihedral and quaternion groups and explore questions like "what if we replace in with a larger root of unity?" and "what if we add a reflection to ?" The delightful answers reveal lesser-known families like the dicyclic, diquaternion, semidihedral, and semiabelian groups, which come to life with visuals such as Cayley graphs, cycle graphs, and subgroup lattices.
