Not evaluated
The sharp constant in random triangle removal (family 188)
The gist
OpenAI presents, in a manuscript announced on October 6, 2026, work on the terminal leave of random triangle removal.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.

To understand ≈ 20 s reading time, estimated
What it changes
What is left at the end of random triangle removal is called the “terminal leave”. If the manuscript held, it would give a sharp estimate of it, with an optimal constant announced by the family title.
What remains unclear
The repository file formalization.yaml marks the Lean (a language in which a computer checks every step of a proof) supplied by OpenAI as “review: status: unchecked”. No third-party check has been read, so it is not known whether the manuscript holds.

Method
A manuscript dated September 25, 2026: “The sharp terminal leave in random triangle removal”. It is listed in CONTENTS.md and classified under the section “Combinatorics” of overview.tex. The repository contains lean/docs/188.md and 1 Comparator statement. 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.
