Finite group actions on spheres, orbit category, chain complexes, COHOMOLOGY, REPRESENTATIONS, INDUCTION
We give a general framework for studying G-CW complexes via the orbit category. As an application we show that the symmetric group G = S-5 admits a finite G-CW complex X homotopy equivalent to a sphere, with cyclic isotropy subgroups.
