WebMar 24, 2024 · A total order (or "totally ordered set," or "linearly ordered set") is a set plus a relation on the set (called a total order) that satisfies the conditions for a partial order plus an additional condition known as the comparability condition. A relation <= is a total order on a set S ("<= totally orders S") if the following properties hold. 1. Reflexivity: a<=a for all a … WebAug 31, 2024 · Chains and Antichains: Proof. Suppose ( P, ⪯) is a poset, and let L = { a, b } ⊂ P with a ⪯ b. Let S = P × L. Let B be the largest possible subset of P such that B … lowest traffic times
