First, I wrote down 234,243,324,342,432 and 423. After that, I wrote the number one in front of all of them so you already get 6 possibilities. Then I just changed the number one with the number two. After that, I switched 2 with 3 and 3 with 4. so then you add all of them together so you get 24 possibilities or at the start you can just do 6 times 4 to also get 24 possibilities.
