With AI becoming increasingly capable of solving difficult problems, I've been wondering why LANA hasn't released its Lean formalization, even in an incomplete state. Even if the proofs themselves are unfinished, the definitions and overall formal framework would already be valuable to the community.

That's one of the reasons I decided to publish my own independent Lean formalization of IUT, developed with the help of Fable5. I also shared it on 4chan and 5ch in case anyone is interested in taking a look.

but, comment is japanese only.
