I tend to believe that it is finite ? For example, if we take a surface of genus 2, and fix a hyperbolic metric on it,then aren't there exactly two ways of cutting it into two pants ? I know one can give ( Dehn )twists along a geodesic along which we cut, but would that not change the metric ?</p> <p>Thanks !</p>
