## Binomial coefficient

A combination of $n$ elements taken $k$ at a time is a set of $k$ elements chosen from the given $n$ elements. In this context, sets that differ only in the order of the elements (but not in their composition) are considered identical. It is precisely this property of combinations that distinguishes them from permutations.
