WebMay 10, 2024 · When calculating the Euler Characteristic of any regular polyhedron the value is 2. Since a sphere is homoeomorphic to all regular polyhedrons, the sphere ought to have a Euler Characteristic of 2 as well. So: V − E + F = 2. holds true. A sphere obviously do not have vertices nor edges, which ought to mean they have 2 faces, which i assume ...
