So,

This is permutations.

To find all of the possible choices, you will have the number of seats with the mathematical exclamation mark after that number.

4 + you = 5 people
5! = 120

You and your 4 friends can sit in your seats 120 different ways.

Don't waste your time trying to find all 120 of them though.
