Abstract

An equiangular hyperbolic Coxeter polyhedron is a hyperbolic polyhedron where all dihedral angles are equal to $π ∕ n$ for some fixed $n \in ℤ$ , $n \geq 2$ . It is a consequence of Andreev’s theorem that either $n = 3$ and the polyhedron has all ideal vertices or that $n = 2$ . Volume estimates are given for all equiangular hyperbolic Coxeter polyhedra.
