Coverage & review
Coverage of this curation
Canonical question, exact result scopes, proof evidence, contributors, history and explanatory examples.
Formal proofs: SAT/DRAT certificates are available in the immutable archive. They are computational proof evidence, not an identified Lean or Isabelle theorem; OpenMath has not executed the certificates.
AI-assisted work: Model assistance is self-reported by Putman; specific model versions are not identified in the selected disclosure.
Search scope & review
Selected primary manuscript versions and their cited original literature, checked on 14 October 2026. This is not an exhaustive literature review.
