In English we use the word "combination" loosely, without thinking if the order of things is important. In other words: "My fruit salad is a combination of apples, grapes and bananas" We don't care what order the fruits are in, they could also be "bananas, grapes and apples" or "grapes, apples and bananas", its the same fruit salad.Combinatorics is the study of finite structures.

We can perform integral elementary row operations on the matrix (Rλµ), except for multiplying a row by a scalar, without changing the abelian group generated by the rows. Since dµ divides Rλµ we can obtain the diagonal matrix (dµ) by such row operations, and the proof follows.
