The number of these that are of size k drawn from a group of n items is n factorial divided by quantity n minus k end quantity factorial.
Cayley's Theorem states that every group is isomorphic to a group of these entities. They can be written as a product of transpositions. They are bijections from a set to itself and for a set of size n there are N factorial of them. The number of these that are of size k drawn from a group of n items is n factorial divided by quantity n minus k end quantity factorial. For 10 points, name these items which are different orderings without repetition of a list of items which should not be confused with combinations.
