WebMar 3, 2024 · Permutations refer to: The number of ways we can arrange a list of things, and the order of things does matter.; E.G. If we have AB, possible permutations are AB and BA.; I.E. “Singular” A is not a permutation of AB, because the order does matter and B is missing. Combinations refer to: The number of variations we can create from a list of things, the … WebPermutations is a popular topic within discrete math. Our permutations calculator solves for the number of subsets that can be a taken from a set of objects. Unlike Combinations however, the order of the subset matters. Basically, Permutations let you know how many different subsets can be created using the same items, but in different orders.

For example, for , the swap sequence 012 leaves all items in place, while 122 starts by swapping index 0 with index 1, then swaps 1 with 2, and then swaps 2 with 2 (i.e. leaves it in place). This results in the permutation BCA. WebCombination: Choosing 3 desserts from a menu of 10. C (10,3) = 120. Permutation: Listing your 3 favorite desserts, in order, from a menu of 10. P (10,3) = 720.
