This selection of subsets is called a permutation when the order of selection is a factor, a combination when order is not a factor. Stated differently, if the order of the first three changes, then it is considered a new permutation, but if the order of the first three stays the same, (even if the order of the remaining 12 Permutation vs Combination.
