233 = 18 combinations.
There are 18C4 = 18!/[18-4)!4!] = 18*17*16*15/(4*3*2*1) = 3060 combinations.
There are 18 permutations or 5 combinations. And it is one die, many dice. There is no such word as dices or diceses.
3 items each in 3 categories gives 3*3*3 = 27 possible combinations.

There are: 35C3 = 6545 combinations
Combinations of 2: 20*19/(1*2) = 190 Combinations of 3: 20*19*18/(1*2*3) = 1140 Combinations of 4: 20*19*18*17/(1*2*3*4) = 4845 So 6175 in all.
How many combinations of five. Numbers could you get from 1 to 20
There are 6C3 = 20 such combinations.
There are 5C3 = 10 combinations.
The number of combinations is 20C5 = 20!/(15!*5!) = 20*19*18*17*16/(5*4*3*2*1) = 15,504
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
You could make 10*10*10*26*26*26 combinations, or 17576000 combinations.
There are 9C3 = 84 combinations.
There are 32C3 = 32*31*30/(3*2*1) = 4960 combinations. I do not have the inclination to list them all.
