What it changes
A literature search means tracking down results that have already been published. If this search was right, the solution would already appear in published texts. Erdős problem #120 belongs to combinatorics (the study of ways of counting and arranging objects).
What remains unclear
This wiki line cites no text from the literature, names no verifier, and does not say how the variant differs from problem #120. On October 12, 2026, erdosproblems.com listed this problem as “open”.

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-5.4 Thinking. Date given by the wiki: March 14, 2026. Exact text: “Solution to variant problem 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): open (informal_status=open); 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/120. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.
