How to simplify permutations
WebSep 19, 2015 · Compute g f g − 1 if f = ( 1, 3, 5, 6) and g = ( 2, 5, 4, 6) where multiplicative notation is used to indicate composition and f and g are cycles. I have determined g − 1 = ( 2, 6, 4, 5) and thus found g f g − 1 = ( 2, 5, 4, 6) ( 1, 3, 5, 6) ( 2, 6, 4, 5) This is where I am stuck, however. I do not know how to simplify this.

WebThere are 120 ways to select 3 officers in order from a club with 6 members. We refer to this as a permutation of 6 taken 3 at a time. The general formula is as follows. P (n,r)= n! (n−r)! P ( n, r) = n! ( n − r)! Note that the formula stills works if we are choosing all n n objects and placing them in order.
