Released manually constructed Lean4, Isabelle and partial Coq formalizations of640 Putnam competition theorems with original statements and baseline prover evaluations.
Scientific scope
Released manually constructed Lean4, Isabelle and partial Coq formalizations of640 Putnam competition theorems with original statements and baseline prover evaluations. 640theorems in original v1 differ from later672problem releases; v1 reports1697formalizations, later paper counts1692. These are formalization positions, not1697independent mathematical discoveries. No proof or semantic-equivalence replay by WRS.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. 640theorems in original v1 differ from later672problem releases; v1 reports1697formalizations, later paper counts1692.
