How many ways you position 7 people in a circle?

It's 6!=720.

The formula for circular permutation is given by (n-1)!

This is because of the fact that in a circular setting if you move each of the person one way right or left, you still get the same arrangement, and we can do so n times until we get back to the first arrangement.

You need to include the original coordinates of the triangle to answer this. and how much does it translate (move left right up down)
