WebWiener-Hopf matrix factorization requires solving a scalar Riemann-Hilbert on an elliptic surface and the associated genus-1 Jacobi inversion problem solved in terms of the associated Riemann -function. Numerical results for the absolute value of the total velocity potentials are reported and discussed. 1 Introduction The term triple torus is also occasionally used to denote a genus 3 surface. The Klein quartic is a compact Riemann surface of genus 3 with the highest possible order automorphism group for compact Riemann surfaces of genus 3. It has namely order 168 orientation-preserving automorphisms, and 336 automorphisms if orientation may be reversed. • Several genus 3 surfaces
