<p>ok i’m not good at explaining this but i’ll try</p>
<p>there are 6 people sitting around
let’s label the first person as x
to form a ring (round table) , you start at point x and you end up back at point x right
if you substitute 1 for point x, you will have 1 x 5 x 4 x 3 x 2 x 1 = 120 ways</p>
<p>it’s just like doing 6 factorial (6! = 6 x 5 x 4 x 3 x 2 x 1 =720) but you substitute the 6 at the beginning with 1</p>
