Title:Â Mutations of reflections and existence of pseudo-acyclic orderings for type An Abstract:Â In a recent paper by K.-H. Lee, K. Lee and M. Mills, a mutation of reflections in the universal Coxeter group is defined in association with a mutation of a quiver. A matrix representation of these reflections is determined by a linear ordering
