Figure 21.4. 1: Permutations of a set of size 4. Notice that the permutations above have been grouped into pairs, where the two permutations in a given pair have the same two first elements in the same order. From this, we can conclude that there are only 24 / 2 = 12 permutations of size k = 2 from A.
