EXAMPLE

The sequence cannot start with 1 because the first digit is not 8. Let us start with 2: second digit equal to 8. The third digit cannot be 3 because the third digit is not 8. So let it be 4. In the next position we have now 80 because is the minimum number greater than 8 and starting with the digit 8. And so on.
