Cohen's 22 Conjectures on Cyclic Numbers

Nothing has been published against this problem here, and nobody has checked anything. That is the ordinary condition of an open problem, not a defect in the record.

Statement

22 conjectures of Cohen about cyclic numbers (integers with gcd⁡(n,φ(n))=1\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).

Context

OEIS-attached conjectures with documented statements but a one-community audience; the bundle of 22 sits just above the single machine-generated-conjecture baseline.

    "All proofs in the paper were assisted by GPT-5" - a blanket credit across 22 resolutions, with no individual attribution, so the lower tier applies.
