"WebAug 28, 2024 · The action of G on P preserves T and descends to the quotient space F = T / ∼. It is easy to check that every G -orbit in F is discrete, closed, but the map F → F / G is not a covering map (say, at the equivalence class of (0,1)). In this example, F is homeomorphic to the open Moebius band. " - Orbit space of group action
