the above formula calculates the permutations of subsets (r) from the set (n). But I want to calculate the permutations of 3 or more different variables ... so, how many permutations of colourful bookshelves would I have, if I'm stacking
100-1000 books of
2-10 colours on
5-100 shelves Answer by solver91311(24713) (Show Source):
