I will describe a finitely presented subgroup of Monod’s group of piecewise projective homeomorphisms of the real line. This provides a new example of a finitely presented group which is nonamenable and yet does not contain a nonabelian free subgroup. The example is torsion free and of type F∞. A portion of this is joint work with Justin Moore.
