Topic: Solutions to "Theorem Proving n LEAN 4" exercises

Hello,
I am very new here. Does anyone know if there is a solutions document to the exercises in "Theorem Proving in LEAN 4"?
Thx

I am not aware of one, but I have solved almost all exercises up to chapter 5, and plan to solve all exercises in the book. What does the author, devs, and community think about creating a github repo with solutions (perhaps multiple solutions contributed by many authors)? Would it help or hurt education?

I solved all exercises. Do you want me to create a Git repository containing my solutions?

Patrick Massot (Aug 19 2023 at 17:15):

This is a question for @Jeremy Avigad.

Nicolas Rolland (Aug 19 2023 at 17:48):

solutions are mostly useful, to me at least, if one can learn from the style of the proofs

Jeremy Avigad (Aug 19 2023 at 18:57):

It's o.k. by me!

I agree completely, which is why I think the github repo could include multiple proofs, possibly through PRs, as long as they are sufficiently distinct and informative (at the discretion of the owner).

I'm a bit busy, but I'll make the repository eventually.
