The drawing below shows a Hasse diagram for a partial order on the set {A, B, C, D, E, F, G, II, I, J} Figure 3: A Hasse diagram shous 10 vertices and 8 edges. The vertices, rep- resented by dots, are as follows: verter J; vertices II and I are aligned vertically to the right of verter J; vertices A, B, C, D, and E forms a closed loop, which is to the right of vertices II and I; vertex G is inclined upward to the right of vertex E; and vertex F is inclined downward to the right of vertex E. The edges, represented by line segments, between the vertices are as follows: Verter J is connected to no vertex; a vertical edge connects vertices II and I; a vertical edge connects vertices B and C; and 6 inclined edges connect the following vertices, A and B, C and D, D and E, A and B, Е аnd G, and E аnd P. (n) What are the minimal elements of the partial order? (b) What are the maximal elements of the partial order? (c) Which of the following pairs are comparable? (А, D), (J, F), (В, E), (G, F), (D, B), (С, F), (П, І), (С, E)

i. Draw a connected bipartite graph with 5 labelled vertices, {a, b, c, d, e} = V and 5 edges.Based on the graph you’ve drawn, give the corresponding partition π = {V1, V2} and the relationρ ⊂ V1 × V2 corresponding with the edges.ii. Let A be a set of six elements and σ an equivalence relation on A such that the resultingpartition is {{a, b, f }, {c, e}, {d}}. Draw the directed graph corresponding with σ on A.iii. Draw a directed graph with 5 vertices and 10 edges (without duplicating any edges) repre-senting a relation ρ that is reflexive and antisymmetric, but not symmetric or transitive. Notehow these properties can be identified from the graph.
