Powers of cycles? Orders of elements?

  1. Nov 16, 2005 #1
    When calculating powers of cycles, are there any easy steps to use in doing so? I mean...is there a typical relationship when calculating (123)^n?

    Also, is it safe to say that a ceratin n-cycle should have order n or n-1?

    I guess any explanation of orders for group elements would be appreciated. For now I will look some stuff up on mathworld, etc. Thanks for your help.

    isn't it sort of obvious that any cycle of length n has order n?

    hence raising (123) to the nth power is the same as raising it to the least residue of n mod 3?
