Parial Order and Hasse Diagram
Let A={1,2,3,4,6,24,36,72}, Let ≤ be the partial order defined by A≤B if a divides b. Number of edges in the Hasse diagram of (A,≤) is
If A = {1, 2, 3, 6, 9, 18], then number of edges in the poset diagram of poset [A; /] is
Which of the following are one of the maximal and minimal elements respectively of the poset ({2,4,5,10,12,20},/)
Which of the following is/are neither a maximal element nor a minimal element of the poset ({1,2,3,4,5,6},/)?
Let P be the set of all people. Let R be a binary relation on P such that (a, b) is in R if a is a brother of b. Is R symmetric, transitive, an equivalence relation, a partial order relation?
