Can you explain to me how this works? Specifically, how does

the permutation multiplication work. How does (1,3,4,6)(2,3,5)

become the 2 permutations multiplied together. I guess I am lost on

all of it.

4. Let T = (1,3,4,6)(2,3,5) in Ss. Find the index of in So. S61 Solution: If we let H = (r), then we are looking for (S. : H) However, we cannot simply claim that H = 12 because the cycle decomposition for T is not disjoint. Therefore, we need to figure out what the actual disjoint cycle decomposition is. To do that, we need to figure out what is as a permutation, not the given cycles. To do this, just multiply the permutations out 3 4 5 6 1 2 3 4 5 6 3 5 4 2 6 4 5 6 2 1 TE 2 = (1,3,4,6)(2,3,5) = (338 56 1 3 1) Following the process we did in problem 3 to break down into its cycle decomposition, we see that T=(1,3,5, 2, 1,6) and is itself a cycle of length 6. Therefore, |M| -6 and (S6: H) 6! 120. 6
