Apache-2.0: you can use it for free, also in a commercial product. Keep the licence notice.
Quick checks from public data. They help, but they are no guarantee.
What it is
A sorry-free Lean 4 formalization of the Classification of Finite Simple Groups, built on Mathlib and TauCeti. It follows the first generation proof and checks the statement that every finite simple group is isomorphic to a group on an explicit classification list.
Who it's for
Lean and Mathlib users interested in formal verification of group theory and finite group classification
