WebThere are two cases of circular-permutations:- (a) If clockwise and anti clock-wise orders are different, then total number of circular-permutations is given by (n-1)! (b) If clock-wise and anti-clock-wise orders are taken as not different, then total number of circular-permutations is given by (n-1)!/2! Proof (a): Web2. mar 2024 · However if rotation symmetry is taken into account, there are five ways for people to sit at the table which are just rotations of each other. So using symmetry the answer is 24. So I understand why it's 5! for the first part. Order matters so it's a permutation without replacement, so $\frac{n!}{(n-r)!}$ = $\frac{5!}{(5-5)!}$ = 5! = 120 pitbull bullies xl
