Authored summary

The cited American Mathematical Society article says that the existence of an odd perfect number is unknown. The source and public status were checked on 2026-07-31. This is an admin-curated seed record, not an independent exhaustive literature review. Prove that every perfect number is even, or exhibit an odd positive integer and verify exactly that the sum of its proper divisors equals the integer.

The record cites sources for its explanation.

2Authored explanation

The cited American Mathematical Society article says that the existence of an odd perfect number is unknown. The source and public status were checked on 2026-07-31. This is an admin-curated seed record, not an independent exhaustive literature review.

A complete resolution must satisfy this condition: Prove that every perfect number is even, or exhibit an odd positive integer and verify exactly that the sum of its proper divisors equals the integer.
