On the optimality of the ideal right-angled 24-cell
arXiv:1211.2944 · doi:10.2140/agt.2012.12.1941
Abstract
We prove that among four-dimensional ideal right-angled hyperbolic polytopes the 24-cell is of minimal volume and of minimal facet number. As a corollary, a dimension bound for ideal right-angled hyperbolic polytopes is obtained.
