EXAMPLE
The first few antidiagonals are:
1,
1,2,
1,3,2,
1,4,4,3,
1,5,7,8,3,
1,6,11,19,10,4,
1,7,16,41,32,16,4,
1,8,23,81,101,68,20,5,
...
CROSSREFS
For some rows, columns, diagonals see A006380, A006281, A006382, A006383.
The second row of the array starts 2,4,7,11,16,23, which does not identify it uniquely.
