Published 11 May 2017 in math.GR and math.GT | (1705.03984v3)

Abstract: We construct a family of right-angled Coxeter groups which provide counter-examples to questions about the stable boundary of a group, one-endedness of quasi-geodesically stable subgroups, and the commensurability types of right-angled Coxeter groups.
