Can an exterior algebra $ k\langle x_{1},\dots,x_{n} \rangle/(x_{1}x_{2}-x_{2}x_{1},\dots,x_{1}^{2},\dots) $ can be seen as a skew group algebra?
A skew group ring is defined for example in the introduction of this paper. I read this fact(?) somewhere but I cannot find a group action $G \rightarrow \mathrm{Aut}(k)$ that cooks up the exterior algebra.
