# A formal proof of the Odd Order Theorem

The repository contains a [formal verification](https://hal.archives-ouvertes.fr/hal-00816699/) of 

the [Odd Order Theorem](https://en.wikipedia.org/wiki/Feit%E2%80%93Thompson_theorem) (Feit - Thompson, 1963), 

a landmark result of finite group theory.

The formal proof is based on the [Mathematical Components](https://github.com/math-comp/math-comp)

library for the [Coq](https://coq.inria.fr) proof assistant.
