For a 4-player card game where turn order matters (e.g., who deals first, who plays first), there are exactly 24 distinct seating/playing orders.
This is a permutation of 4 distinct players:
4! = 4 × 3 × 2 × 1 = 24
4 × 3 × 2 × 1 = 24
If you only care about who sits where relative to each other (circular permutations), it's (4-1)! = 6 distinct table arrangements.
But for "playing order" (sequence of turns), the answer is definitively 24.
