In how many ways can 5 people be seated in 8 chairs around a round table?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

For linear arrangements, the number of all possible distinguishable arrangements 
is  8*7*6*5*4, the number of all permutations of 5 different objects from 8 objects.


To account for the circular symmetry, we must divide this number by 8.


It gives the answer to the problem's question  %288%2A7%2A6%2A5%2A4%29%2F8 = 7*6*5*4 = 840.


ANSWER.  For this problem there are 840 distinguishable circular permutations.
