Abstract
We prove that the number of distinct group actions on compact Riemann surfaces of a fixed genus is at least quadratic in . We do this through the introduction of a coarse signature space, the space of skeletal signatures of group actions on compact Riemann surfaces of genus . We discuss the basic properties of and present a full conjectural description.
