=> x = n!/n = (n – 1)!. will lead to the same arrangements for a circular table. Hence one circular arrangement corresponds to n unique row (linear) arrangements. Hence the total number of circular arrangements of n persons is = (n – 1)!.

What is circular permutation with example?
Permutation in a circle is called circular permutation.
