Why are number of combinations always smaller than number of permutations?
The number of combinations is always smaller than the number of permutations. This time, it is six times smaller (if you multiply 84 by 3! = 6 , you’ll get 504). It arises from the fact that every three cards you choose can be rearranged in six different ways, just like in the previous example with three color balls.
