    Place your first person in a seat. Then for the first 3 pictures put a different person in the seat clockwise of him. For each of those 3, put the remaining 2 people in different seats. Boom, 6.

    They are only the same if you can rotate the table so they look exactly the same.

    Yup, so the two pictures you drew are different as you can't rotate one to make the other.

    Why did you move your A? With your 3 you got, just swap the bottom row and keep the top row the same.
