# Mathlib Tactics

This dataset contains tactic invocations with associated goal states from proofs in [Mathlib](https://github.com/leanprover-community/mathlib4/tree/5e932f97dd25535344f80f9dd8da3aab83df0fe6), the mathematical library for the Lean 4 theorem prover, extracted with [lean_scout](https://github.com/mathlib-initiative/lean_scout).

Extracted from the Mathlib commit with the following hash.
