Question

Transcribed Image Text:For each item:
(i) Sketch the directed bipartite graph representing each permutation;
(ii) Use the graph to find the *inverse* of the permutation, and
(iii) Find the number of *inversions* in the permutation and its inverse.
d. \( (6, 3, 7, 2, 5, 1, 4) \)
The following are the same permutations that appear in Exercise 3. For each item:
(i) Exchange the two boxed components, (ii) count the number of inversions in the new permutation, and (iii) check that the new permutation has the opposite sign as the original permutation.
d. \( (6, 3, \boxed{7}, 2, 5, 1, \boxed{4}) \)
