A categorical, semi-simplicial interpretation theory for “triple” cohomology is outlined which uses the groups TORSU n [X ;π] of connected components of certain categories ofK (π,n )-torsors (higher dimensional generalizations of locally trivial principal fiber bundles) to interpret the cohomology groups, i.e., TORSU n [X ;π] [unk]Hn (X ;π),n ≥ 1.
