Find formula and prove it,or how formula are from,about the methods of "R" arrangement into "N" boxes by separate in 4 types.
1.The same thing and the different boxes type
2.The different thing and the different boxes type
3.The same thing and the same boxes type
4.The different thing and the same boxes type
Maybe this will help: Combinations and Permutations.

And also add to this list of things to find:
5. For even number of things and boxes, half of things the same, rest are different and half of the boxes are the same and the rest are different!!
6. For K things with 3 types of things and M boxes with 3 types of boxes, A of type 1, B of type 2, C of type 3 where A + B + C = K and they are put into the M boxes of types X, Y, and Z quantities adding to M. Also, if K < M, then some boxes will be empty after distribution, so formula might be different. We will see when we figure this out...
