(Last updated in October 2018) - dufferzafar/geeksforgeeks.pdf In mathematics, a permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements.The word "permutation" also refers to the act or process of changing the linear order of an ordered set. Each permutation in the sequence that it generates differs from the previous permutation by swapping two . unique permutations. So, we will make the permutations of 2, 3 and 4 by keeping 2 fixed.
