There are 9 1-digit numbers and 16-2 digit numbers. So a 5 digit combination is obtained as:
- Five 1-digit numbers and no 2-digit numbers: 126 combinations
- Three 1-digit numbers and one 2-digit number: 1344 combinations
- One 1-digit numbers and two 2-digit numbers: 1080 combinations
This scheme does not differentiate between {13, 24, 5} and {1, 2, 3, 4, 5}. Adjusting for that would complicate the calculation considerably and reduce the number of combinations.
