Circular Permutation

The document introduces circular permutation as the number of ordered arrangements that can be made of n objects in a circle. It is calculated as (n-1)!. Several examples are provided to illustrate circular permutation for seating people around a table and arranging beads on a bracelet. The document also considers the number of ways 4 married couples can be seated if spouses sit opposite each other [(n-1)!/3!] or if men and women alternate [3! x 4! = 144].
