What is recorded here?
EQP found a proof in 1996 that every Robbins algebra is Boolean, completing a longstanding algebraic problem after earlier human and automated work on sufficient conditions.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
McCune authored the 1997 paper; Winker’s earlier conditions are separately credited. EQP proof discovery and later Otter reconstruction are distinct. WRS replays archived certificates with two custom local checkers; it has not rerun the original search or a Lean/Coq/Isabelle kernel, and has no independent reviewer or provider attestation.
