WebJan 20, 2009 · A well-known fact is that every automorphism of the symmetric group on a set must be inner (whether the set is finite or infinite) unless the set has exactly six elements (4, § 13).A long-standing conjecture concerns the analogue of this fact for the group A (S) of all order-preserving permutations of a totally ordered set S.The group A (S) is lattice … WebAug 22, 2016 · the answer said the sample is ORDERED and I dont understand why. My thought is that if I draw three balls, for example: red, red, blue. blue, red, red. red, blue, red. They are all the same, because I just need to know what colour and how many of each colour were drawn. In this case, 2 red and 1 blue, and the order does not matter.

WebFor a permutation, the order matters. Example: How many different ways can 3 students line up to purchase a new textbook reader? Solution: n-factorial gives the number of permutations of n items. n! = n(n - 1)(n - 2)(n - 3) … (3)(2)(1) Permutations of n items taken r at a time. P(n,r) represents the number of permutations of n items r at a time. WebAlright, so this is where permutations start to be useful. Although, I think a lot of things like this, it's always best to reason through than try to figure out if some formula applies to it.

Permutation vs Combination: Differences & Examples

In some applications, the elements of the set being permuted will be compared with each other. This requires that the set S has a total order so that any two elements can be compared. The set {1, 2, ..., n} is totally ordered by the usual "≤" relation and so it is the most frequently used set in these applications, but in general, any totally ordered set will do. In these applications, the ordered arran… WebPermutations and combinations are part of a branch of mathematics called combinatorics, which involves studying finite, discrete structures. Permutations are specific selections of elements within a set where the order in which the elements are arranged is important, while combinations involve the selection of elements without regard for order.
