Abstract
If is prime, a compact Riemann surface of genus is called cyclic -gonal if it admits a cyclic group of automorphisms of order such that the quotient space has genus 0. If in addition is not normal in the full automorphism , then we call a non-normal cyclic -gonal group. In the following we classify all non-normal -gonal groups.
