Erdős Problem #42 has status 'solved (lean)'. Statement: **Erdős Problem 42**: Let M ≥ 1 and N be sufficiently large in terms of M. Is it true that for every maximal Sidon set `A ⊆ {1,…,N}` there is another Sidon set `B ⊆ {1,…,N}` of size M such that `(A - A) ∩ (B - B) = {0}`? This was proved for all $M$ by GPT 5.5 Pro (prompted by Sandhu), see discussion thread for more details. Topics: number theory, sidon sets, additive combinatorics. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: N/A.
