DavidKazuo (talk) 18:35, 5 November 2018 (UTC)let me add more substantive information regarding topological genus of orientable surfaces. Regarding the homeomorphic characteritics of a genus 3, lift up the center region so that it forms a "tetrahedral" structure with three holes on the side and one on the bottom. This adds 1 hole to make it a genus 4, but being a "topological surface", the symmetries are different. Now you have four x 3 rotational symmetries, instead of 3 bilateral, and 3 rotational symmetries. You also have 4 more holes that are dual to the original holes, that are inside the surface going around each hole!
