As Prof. S. N. De said
"A permutation of a set is defined as an arrangement of its members into a sequence or if the set is already ordered, a rearrangement of the elements of that set. It also refers to the process of changing the linear order of an ordered set. For example, let us assume there are three persons A, B and C sitting beside each other. The different ways in which this sitting arrangement is possible are: ABC, ACB, BAC, BCA, CAB and CBA i.e. there will be 6 ways. Hence, the number of permutations of 3 different things is 6."
