Key Points: Circular Permutations
- The number of circular permutations of different objects = (n − 1)!.
- If the clockwise and the counterclockwise orders are not distinguished, then the number of ways = \[\frac{1}{2}\left(n-1\right)!\].
- The number of ways in which n objects of which p are alike, can be arranged in a circular order is \[\frac{(n-1)!}{p!}\].
- Number of circular permutations of n different objects taken r at a time.
a. When clockwise and anticlockwise orders are taken as different = \[\frac{^nP_r}{r}\].
b. When clockwise and anticlockwise orders are not to be considered different, is = \[\frac{^nP_r}{2r}\].
