COMMENTS
The fixed points of A034690 are 1 and 15, these are the only numbers not appearing in this table. All other positive integers appear exactly once.
Is there a simple explanation why row 7 seems to grow significantly faster than the neighboring rows?
From row 21 on, the terms become very large: cf. A094501 which is the first column with 15 prefixed.
