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.

Sequence in context: A062001 A181847 A209562 * A239030 A165999 A049280

Adjacent sequences:  A259341 A259342 A259343 * A259345 A259346 A259347
