A permutation is an arrangement of items in a particular order. A combination is a collection of items chosen from a set, where the order of selection doesn't matter.
When the order matter it is an example of?
It has to be exactly 4-7-2. So, in Mathematics we use more precise language: When the order doesn't matter, it is a Combination. When the order does matter it is a Permutation.
Does order matter in permutations?
If the order doesn't matter then we have a combination, if the order do matter then we have a permutation. One could say that a permutation is an ordered combination. The number of permutations of n objects taken r at a time is determined by the following formula: P(n,r)=n!
