The proposed roadmap #271 for surface topology includes combinatorial representations of graphs on surfaces which is intended to serve as the foundation for planar graph theory. In particular that roadmap includes the five color theorem, and mentions the four color theorem in the roadmap for a roadmap. I would recommend not accepting both of these pull requests unless they are harmonized. |

Ok, so the goal is to then get your PR merged and I'll reinstruct it to generate a roadmap that incorporates your ideas |

This is meant to be a port from the four color theorem repository in Coq. It is something that I always wanted to do but now with AI it seems to be autoformalisable. Coq has some horrendously ugly proofs, so I think the port will be more idiomatic.
I have generated the roadmap with OpenCode and I have read and iterated upon it, but I haven't completely crossed all t's.
I'm not sure if this is in scope for Tau Ceti, but it would be cool if we could port some major projects from other proof assistants.
