FINDING: Search results are a mixed bag of Numberphile/Veritasium videos on open problems (Hadwiger-Nelson, odd perfect numbers, Catalan's conjecture, Josephus problem, zero division) plus one unrelated arXiv paper on omnidirectional video quality assessment. No single unified mathematical discovery emerges. MATH: - Hadwiger-Nelson: chromatic number of the plane χ(ℝ²) — known bounds 5 ≤ χ ≤ 7 (recent lower bound 5 via de Grey's unit-distance graph, 2018). No exact value. - Odd perfect numbers: N odd, σ(N) = 2N. No existence proof; known constraints (e.g., N > 10^1500, at least 101 prime factors). - Catalan's conjecture (proved 2002, Mihăilescu): only consecutive perfect powers are 8 and 9 → x^a − y^b = 1 has unique solution 3² − 2³ = 1. - Josephus problem: recurrence J(n,k) = (J(n−1,k)+k) mod n, J(1,k)=0; closed form for k=2: J(n) = 2(n − 2^⌊log₂ n⌋) + 1. - Zero division: undefined; 0⁰ is indeterminate in limits, convention 1 in combinatorics.
