Number of posets with n elements
WebA subset A of a semigroup S is called a chain (antichain) if ab∈{a,b} (ab∉{a,b}) for any (distinct) elements a,b∈A. A semigroup S is called periodic if for every element x∈S there exists n∈N such that xn is an idempotent. A semigroup S is called (anti)chain-finite if S contains no infinite (anti)chains. We prove that each antichain-finite semigroup S is … Web17 feb. 2024 · poset A = { (1 2), (1 3), (1 4), (1 6), (1 12), (2 4), (2 6), (2 12), (3 6), (3 12), (4 12), (6 12)} So, now the Hasse diagram will be- In above diagram, 1 is the only element that divides all other elements and …
