What Hacker News says
3 sourcesInteresting project for anyone who want to start learning lean and contribute to a project.
The project as described in the article is to produce a graph (Poset) where each node is a law (say the commutativity equation for example) and each edge is either a proof of implication or a proof of a non-implication, since this graph is infinite the project limits the laws considered to up to 4 applications of the binary operator.
The main goal is not the proofs themselves but experimenting in doing math in a matter that's more similar to software engineering in the open source community.
The collaborative aspect of the project is to write a proof for each kind of edge (implication and not_implications) between the 4694 considered nodes.
There's also the advantage that a GitHub CI running lean will be setup to automatically check if the pull req

uests adding theses edges are right or wrong without the need for a human to do the checking of the proofs in their head.
