Presentations of Coxeter groups of type , , and using prefix-reversal generators

arXiv:2010.13274

Abstract

Here we provide three new presentations of Coxeter groups type , , and using prefix reversals (pancake flips) as generators. We prove these presentations are of their respective groups by using Tietze transformations on the presentations to recover the well known presentations with generators that are adjacent transpositions.
