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.

Checked Oct 14, 2026 · independent review pending.

  • Independent OpenMath mathematical review and external proof execution remain pending.
