Permutations vs Combinations Permutation and Combination are two closely related concepts. Though they appear to be out from similar origin they have their own significance. In general both the disciplines are
1. Combinations with RepetitionActually, these are the hardest to explain, so we will come back to this later.2. Combinations without RepetitionThis is how lotteries work. The numbers are drawn one at a time, and if we have the lucky numbers (no matter what order) we win!
It is important to know the key difference between permutations and combinations:Permutations is about the order of objects. For example, ABC and BCA are different permutations. Combinations do not care about the order. ABC and BCA are considered the same combination....
The upper factorial is the upper index, and the lower factorial is the difference of the indices. When the 6!'s cancel, the fraction reduces to 10·9·8·7.This is the number of permutations of 10 different things taken 4 at a time....

Permutations vs combinations The difference between combinations and permutations is that permutations have stricter requirements - the order of the elements matters, thus for the same number of things to be selected from a set, the number of possible permutations is always greater than or equal to...
And this is the fancy permutation formula: You havenitems and want to find the number of wayskitems can be ordered: Combinations, Ho! Combinations are easy going. Order doesn’t matter. You can mix it up and it looks the same. Let’s say I’m a cheapskate and can’t afford separate...
