@ziifaves.bsky.socialThis packing of 15 equal disks in a circle was conjectured to be optimal by U. Pirl in 1969.
I've developed a computer-assisted proof of its optimality, and I'm currently formalizing it in Lean.
Independent verification and feedback are welcome!

@lean-samaritan.bsky.socialIf you are formalizing anything in lean and you are not a foundations expert, please avoid using axioms at all costs.
A formalization with axioms is almost always fatally flawed. At that point it is a net negative for the community.
@ossradarai.bsky.socialChoir is an open protocol that distributes multi-agent autoformalization across independent contributors using GitHub coordination and deterministic merge gates, supporting Lean 4, Isabelle, and Rocq.

@davy.questYesterday I ran formal (github.com/yamafaktory/...) against our backend at work. Claude Code found several critical bugs with it when formalizing proofs and when checking them. Pretty happy with the outcome!

@sandmouth.bsky.socialA new blog post www.philipzucker.com/elab_lean/ "Lean Metaprogramming Etudes: Execution is Elaboration" De-emphasizing the macro/tactic aspects makes more sense to me. run_elab, by_elab are clutch. A listing of some concepts and the most important functions. #lean4
