COMMENTS

Based on A016825=2,6,10,..., the family is

N16(1)=1, followed by 2's =A040000,

N16(2)=1,2,3,4,5, followed by 6's =A101272,

N16(3)=1,2,3,4,5,6,7,8,9, followed by 10's, not in the OEIS,

N16(4)=1,2,3,4,5,6,7,8,9,10,11,12,13, followed by 14's, idem.

The N16(n) gives the successive columns beginning at row 1, 3, 9, 19, ... =A058331.

Sum of every row: n =A000027.
