WebApr 6, 2024 · A note on regular polyhedra over finite fields. Caleb Ji. Grothendieck proposed a theory of regular polyhedra over finite fields in Section 4 of \textit {Esquisse d'un Programme}. He isolates certain key parameters from the automorphism groups of regular polyhedra, which can be extended to any genus and specialized to various rings.
