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.

10. strobe

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

11. anilorap

12. strobe

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

My apologies, I could only see the first drawing in each of your pictures as my window is small. In your second picture they are the same yes,

Okay now for each of those pictures, just swap over the 2 on the bottom and you have your 6.

What is your picture trying to show? You have 6 different tables there like I told you.

25. anilorap

the first three are different arrangements but the three next it looks the same if u turn the table

26. anilorap

27. strobe

You're wrong, look more carefully. You have 6 distinct tables.
