Confirming the Order of Permutation: LCM = 8

[WM07]

Can you tell me if my answer is correct?

in (1 2 3 4) (1 2 3 4) The order of permutation is LCM = (4, 4) = 8

The order of the permutation is indeed the LCM of the order of each. However, you may want to double check your math. LCM(4,4) is not 8.

Thank you, I get the least common multiple is 4 am I right?

You might want to double check your method for finding the order.

Yes, write in DISJOINT cycles and the order is then the least common
multiple of the lengths of the cycle.
