EXAMPLE
The only digit of the first term [1] states that the first digit of this integer is a "1" - which is true.
The second term [11] says twice that the first digit of this integer is a "1" - which is (doubly) true.
The third term [12] states that the first digit of this integer is a "1", the second digit of this integer is a "2" - which, again, is true.
The fourth term [22] says twice that the second digit of this integer is a "2" - which, again, is (doubly) true.
Etc.
This sequence shows all such integers, starting with the smallest one.
