To understand ≈ 20 s reading time, estimated
What it changes
Problem #223 belongs to geometry, around distances between points. If the full solution held, the problem would be dealt with in full; the wiki marks the entry as a full resolution. A literature search consists of finding results that have already been published.
What remains unclear
The sources read do not say which solution was found or in which text. No third-party verification is on record, and 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(a), “Literature search” (secondary contribution). Humans named by the wiki: none; AI system: GPT-5. Date given by the wiki: October 13, 2025. Exact text: “Full solution found”; green flag (“full resolution”, according to the wiki's legend). 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); no formalised solution known (formal_status=unformalized). This status concerns the problem, not this contribution. Problem page not read by DiscoverIA: https://www.erdosproblems.com/223. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.
