Not evaluated
Saxl's conjecture and universal tensor squares (family 205)
The gist
OpenAI claims, in two manuscripts announced on October 6, 2026, a proof of Saxl's conjecture and results on universal tensor squares.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.
AI draft, not reviewedWhat has not been reviewed?
Text written by an AI (DiscoverIA pipeline), on . The status and its sources come from the registry; only the explanatory text has not been reviewed. A reported error is corrected, then the text is reviewed.

What it changes
If the manuscripts hold, the first would provide a proof of the conjecture by a method its title calls 'cyclic polytabloid'. The second would concern symmetric groups.
What remains unclear
It is not known whether a third party has evaluated these manuscripts: no evaluation is recorded in the sources read. The Lean (a language in which a computer checks every step of a proof) is supplied by OpenAI itself, and formalization.yaml marks its review as 'unchecked'.

The result is declared neither right nor wrong.
To move to “Under review”: a public review under way. To “Peer reviewed”: a journal publication or a review by named experts.

Method
OpenAI's repository holds two manuscripts dated September 24, 2026: 'Universal Tensor Squares for Symmetric Groups' and 'A Cyclic Polytabloid Proof of Saxl's Conjecture'. The file lean/docs/205.md describes the scope of the Lean formalisation, with 2 Comparator statements. DiscoverIA status: not evaluated, meaning that no third-party evaluation has been found in the sources read. Set on October 12, 2026 from github.com (page read, quotation checked word for word: “describes the scope of the Lean formalization”).
Limits
No named third party: the recorded checks come from the claimant or from a platform tool. The claimant supplies a Lean proof; as of this date, DiscoverIA has found no independent verification of this proof or of the result.
