Mathematical structure of finite generalized symmetries above two dimensions

This record was signed by PubPhys and added to the public log. Download the proof and check it with the open verifier: it recomputes every fingerprint, checks the PubPhys signature against the published key, finds the entry in the log and checks the Bitcoin date, without relying on this site.
