Abstract

Let $G$ be a group coacting on an Artin–Schelter regular algebra $A$ homogeneously and inner faithfully. When the identity component $A_{e}$ is also Artin–Schelter regular, providing a generalization of the Shephard–Todd–Chevalley theorem, we say that $G$ is a dual reflection group for $A$ . We give two examples of dual reflection groups of order $16$ and study algebraic and geometric properties of three associated Artin–Schelter regular algebras of dimension four.
