ruzsaSzemerediNumber

(α : Type u_1) → [DecidableEq α] → [Fintype α] → ℕ

The Ruzsa-Szemerédi number of a fintype is the maximum number of edges a locally linear graph on that type can have. In other words, ruzsaSzemerediNumber α is the maximum number of edges a graph on α can have such that each edge belongs to exactly one triangle.
