Question
The image of 9 is 1 not 6 there is a mistake I need parts 4-5-6-7
Part B: Let S, be the symmetric group and let a be an element of S, defined by:
1
2 3
4 5 6 7 8 9
).
a =
5 4 3
2 9 8 6 7 6
1) Write a as a product of disjoint cycles.
2) Determine the order of a.
3) Calculate a2018
4) Find the smallest integer n such that an+3 = a.
5) Prove that a is an odd permutation.
6) Let ß = (7 3)(1 5 4). Determine aß-la.
7) Show that for any permutations a and ß in Sn, a*ß and ß have the same parity.
