PERMUTATION Each of the different arrangements which can be made by taking some or all of a number of things is called a permuta-tion. whenever the order is important, permutation is used. The number of r-combinations with repetition allowed (multisets of size r) that can be selected from a set of n elements is r + n 1 r : This equals the number of ways r objects can be selected from n categories of objects with repetition allowed. All the above formulas are defined for Number of Permutations or Combinations of r objects chosen from n objects. Permutations with Repetition sets give allowance for repetitive items in the input set that reduce the number of permutations: Permutations with Repetition of the set {A A B}: {A A B}, {A B A}, {B A A} The number of Permutations with Repetition is not as large, being reduced by the number and count of repetitive items in the input set. Today: permutations (without repetition) combinations (without repetition) k-permutations (without repetition) + problems leading to counting selections Beware!While solving real life problems we usually need to split a complex problem into several sub-cases, complex selections/arrangements, during. In our case, we get 336 permutations (from above), and we divide by the 6 redundancies for each permutation and get 336/6 = 56. # of 4-digit numbers without repeated digits.
