To understand ≈ 20 s reading time, estimated
What it changes
The wiki sees a formalisation here: if it held, it would allow the proof it targets, that of van Doorn and Tao (2025), to be checked by computer. Problem #1102 belongs to number theory.
What remains unclear
The wiki does not name the formal language on this line. The sources read do not say whether anyone has checked the formalisation, or whether the formalised statement matches that of the problem. A verification published after the wiki's freeze would not appear there.

this status is an unofficial crowdsourced classification of the problem
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 system: Aristotle. Date given by the wiki: February 23, 2026. Exact text: “Formalization”. Proof to formalise: van Doorn and Tao (2025); 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): resolved other than by a yes-or-no answer (informal_status=solved); 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/1102. 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.
