With 4 digits you can have 24 = 16 combinations.
1 combination with 0 digits;
4 combinations with 1 digit: 1, 2, 4 and 8
6 combinations with 2 digits: 12, 14, 18, 24, 28 and 48
4 combinations with 3 digits: 124, 128, 148 and 248
1 combination with all 4 digits.
In a combination the order of digits is not relevant so that 124 is the same as 142.
