| If you delete the first occurrence of each n, the remaining sequence is the original sequence; thus the sequence contains itself as a proper subsequence (infinitely many times).

FORMULA
| a(n)=number of the row of array A125153 that contains n.
|
|
|
EXAMPLE
| 1 is in row 1 of A125153; 2 in row 2; 3 in row 3;
4 in row 1; 5 in row 4; 6 in row 2, so the fractal
sequence starts with 1,2,3,1,4,2
