A nonamenable finitely presented group of piecewise projective homeomorphisms

In this article we will describe a finitely presented subgroup of the group of piecewise projective homeomorphisms of the real projective line. Th is in particular provides a new example of a finitely presented group which is nonamenable and yet does not contain a nonabelian free subgroup. It is in...
