WebHurwitz surface (plural Hurwitz surfaces) ( geometry ) A compact Riemann surface with precisely 84( g − 1) automorphisms , where g is the genus of the surface. This number is … Websurfaces exist are as rare as perfect cubes; whereas one can deduce from [SPW06] that for the good genera there have to be a lot of Hurwitz surfaces. Similarly as for Hurwitz surfaces there is a bound on the order of the translation groups of translation surfaces of genus g, namely c(g) = 4g − 4. It is achieved only for special g’s.
