Erdős Problem #7

retractedconfidence 70%

VibeMathed reports this item as retracted. VibeMath preserves that report as a source assertion and has not independently authored a plain-language mathematical explanation.

Precise statement

Can there be a finite covering system of the integers with distinct moduli, all of which are odd and greater than $1$?

The source statement is reproduced for indexing with attribution. Mathematical correctness requires domain-expert or mechanical review. VibeMath has not independently audited statement fidelity, correctness, priority, or novelty.

What AI did

Aristotle

Both the failed formalization and the audit that exposed its false axiom were AI-assisted.

Provider: Harmonic · Prompt public: unknown · Independence: unknown

Verification boundary

contested

Claim withdrawn; see the claim issue. Recorded because failed formalizations are part of the honest history of AI mathematics.

Correctness: challenged · statement fidelity: unaudited · peer review: none

What remains uncertain

The claimed Lean proof that no such covering system exists was withdrawn after audit: its central axiom asserted that a product of factors greater than one is less than one, and a statement-fidelity audit confirmed the gap. The problem remains open.

  • VibeMath has not independently verified the mathematical claim.
  • AI-attempt independence and training-data exposure are unknown unless explicitly documented.
  • The claimed Lean proof that no such covering system exists was withdrawn after audit: its central axiom asserted that a product of factors greater than one is less than one, and a statement-fidelity audit confirmed the gap. The problem remains open.
