    I don't quite get the Q-:( In how many ways you can place them `in a circle`?

    i still don't understand what they mean by placing these squares into a circle. Can someone explain to me what is exactly happening?

    example assume the colored circles are objects \(\large \color{black}{\begin{align} &\normalsize \text{in how many ways can u place the objects in a circle} \hspace{.33em}\\~\\ \end{align}}\)

    All I can tell you is that if you rearrange them in different order, then the number of these rearrangements is going to be equivalent to: \(\large\color{black}{ \displaystyle 8{\rm P}8=\frac{8!}{(8-8)!} =40320 }\) But I am not sure how much that relates to the question, because I still don't actually understand the case in the question.

    so i was right then? you are asking about the number of all possible permutations of these objets

    wait, you are saying now the answer is actually 7!, (not 8!) ?

    Maybe you are placing 7 of these circles, into the remaining circle, and want to find the number of the permutations of the 7 circles' placement into that remaining circle?

    becuase I don't really see how 8P8 can be equal to 7! must be we missed the correct interpretation of the Q
