[edit]- Add hypergroupoid https://ncatlab.org/nlab/show/hypergroupoid
- Give examples by discussing postnikov tower (see talk page there)
- Discuss how crossed complexes/strict globular groupoids only model some homotopy types
- Remark that homotopy types have the additional group cohomology data associated from the postnikov tower
- Question: Does there exist a definition of algebraic homotopy types as this data? A strict infinity groupoid together with a sequence of group cohomology classes?
