I know this is a physics group, but then I think you guys can answer me .. anyone can explain how circular permutation work? From the explanation from the book, it is understood that if CW $\ne$ ACW , it is $(n-1)!$. if CW $=$ ACW, $(n-1)!/2$ . . . but then from the example that it give, it confuses me..help? test tomorrow >.<

    What is $(n-1)!$ or $\frac {(n-1)!}2 ?$ By CW=ACW do you mean that reflections are considered identical? Please state your question more clearly, instead of leaving us guessing.2012-09-03
