Abstract : Coxeter triangulations are triangulations of Euclidean space based on a simple simplex. By this we mean that given an individual simplex we can recover the entire triangulation of Euclidean space by inductively reflecting in the faces of the simplex. In this paper we establish that the quality of the simplices in all Coxeter triangulations is $O(1/ √ d)$ of the quality of regular simplex. We further investigate the Delaunay property (and an extension thereof) for these triangulations. In particular, one family of Coxeter triangulations achieves the protection $O(1/d 2)$. We conjecture that both bounds are optimal for triangulations in Euclidean space.
