Here's another question I'm lost on:
"Show that the permutation [itex]\psi [/itex] contained in [itex]S_{10}[/itex] of order 20 is odd"
I know that the order of the permutation is the least positive integer n such that [itex]\psi^n [/itex] is the identity permutation.
I don't know how to check whether the permutation is odd. Even if I did, I still doubt I'd know what to do from there on using the information I've got.
Thanks again.
