Why this formula fits
This is a circular permutation problem because the order around the table matters, but rotating the same full seating does not create a new arrangement.
Does order matter? Relative order matters, but a full rotation of the same seating is still the same circular arrangement.
Is repetition allowed? Repetition is not allowed because each guest occupies one seat exactly once.
Worked solution
8 distinct items around a circle can be arranged in 5,040 ways.
- Input: n = 8
- Formula: (n - 1)!
- Substitute: (8 - 1)!
- Steps: fix one seat and arrange the remaining 7 items
- Result: 8 distinct items around a circle can be arranged in 5,040 ways.
