1, divided into two types:

(1) Three dollars for one person and one for the other three.

First, take three of the six blocks as a whole, that is, C (6 6,3), that is, the combined score.

Then the combination of the whole and the other three pieces are distributed to four people, which is the ranking score, that is, P (4 4,4)

Total * * * has c (6 6,3 3) * p (4 4,4) = 480.

(2) Two pieces for two people and one piece for two others.

First, take two of the six pieces as a whole, that is, C (6 6,2), and then take two of the remaining four pieces as another whole.

C (4 4,2), and then arrange these two moving people with two or four other people, which is P (4 4,4).

The total is c (6,2 2) * c (4 4,2 2) * p (4 4,4) =1080.

There are two ways to merge: 480+ 1080= 1560.

The question is how many people? If there are four people, I don't think there can be 126 kinds. Please make it clear.

I wrote so much. If in doubt, please accept. Thank you.
