To understand ≈ 20 s reading time, estimated

What it changes

The wiki sees this as a formalisation, that is writing a proof in a language that a computer can check. If it held, the proof concerned would exist in that form. Problem #434 belongs to number theory (the study of the properties of integers).

What remains unclear

The wiki designates the formalised proof only as “Continued from [433] formalization”: the sources read do not say what it covers, or what formalization [433] is. They name no verifier and do not name the formal language. A verification published after the wiki's freeze would not appear there.

Method

Source: the “AI contributions to Erdős problems” wiki of the teorth/erdosproblems repository (a repository presented by Terence Tao in his blog post of August 31, 2025); frozen on June 30, 2026 (commit c8ad430, “freeze”) and read on October 12, 2026 in the git repository. Category 2(b), “Formalization” (secondary contribution). Humans named by the wiki: none; AI systems: Aristotle, Claude Opus 4.8. Dates given by the wiki: “24 Feb-29 May, 2026”. Exact text: “Formalization”. Proof to formalise: Continued from [433] formalization; wiki flag on this proof: green (“full resolution”, according to the wiki's legend); the wiki does not name the formal language on this line. Literature cited by the wiki: none. Status of the problem in the teorth/erdosproblems community database (data/problems.yaml, unofficial classification, snapshot of October 12, 2026 with no commit identified, current state, not that of June 2026): proved, answered in the affirmative (informal_status=proved); a solution has been formalised in Lean (formal_status=Lean). This status concerns the problem, not this contribution. Problem page not read by DiscoverIA: https://www.erdosproblems.com/434. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.

Limits

Nature: formalisation (an already known result translated into a language a machine can check), not a discovery. DiscoverIA has not checked this contribution itself.
