Each model contains the five figures in some order, such as ABCDE. There are indeed 5! = 120 possible models. We have 119 of the 120 possible models and they are all lined up next to each other on a very long shelf. If we only had three models ABCDE, ABCED, and EDCBA, then this might look like ABCDEABCEDEDCBA But we have 119 of them, so there are 119*5 figures on the shelf. You get to ask which figure is in a specific position. For my example, the first position is A, the second is B, the sixth is also A, etc.
