number-theory / Elementary number theory
22 conjectures of Cohen about cyclic numbers (integers with $\gcd(n, \varphi(n)) = 1$) settled at once - 16 proved, 6 disproved - together with a complete resolution of a related OEIS problem on sequences whose running averages are Fibonacci numbers (Fried's Conjecture 2).
