Lean Proof-or-Refute 300 Lean Proof-or-Refute 300 is a compact collection of 300 formal reasoning problems grounded in Lean 4 and Mathlib. Each problem starts from a verified Mathlib theorem, makes one small numerical or operator mutation, and asks the model to return either: a Lean certificate proving the mutated proposition; or a Lean certificate proving the exact negation of the complete proposition. The model receives the related source theorem, a bounded source excerpt… See the full description on the dataset page: https://huggingface.co/datasets/xlr8harder/lean-proof-or-refute-300.
