The Attempt at a Solution
I am finding the orders of permutations.
I know that you first find the orbits or cycles I don't know the difference (but I should).
This is what my professor said:
If you have (1345)(897) the orders are 4 and 3 respectively. If 4 and 3 are relatively prime then you just multiply 4 and 3 to get 12. So the order of the both is 12.
Now if you have (1345)(6,7,8,9,10,11) the orders are 4 and 6 respectively. So now you look at the Least Common Multiple
4, 8, 12 and 6, 12 and so the order is the least common multiple which is 12.
But in my problem I have (135)(264)(7), 7 is fixed and I don't know what to do when I have 3 of them.
The orders should be 3, 3, 1, but I don't know how to combine them to get the order of the entire thing.
