Erdős Problem #647 has status 'verifiable'. Statement: Let $\tau(n)$ count the number of divisors of $n$. Is there some $n > 24$ such that $$ \max_{m < n}(m + \tau(m)) \leq n + 2? $$ Topics: number theory. Erdős prize: £25. Statement is machine-verified in Lean (formal-conjectures). OEIS: A062249, A087280.
