The array begins as follows. The rows are shown in the appropriate order for looking at the first quadrant (that is, row 0 is at the bottom, then row 1, and so on):
row 7 = 1, 0, 0, 1, 1, 0, 1, 0, 1, 1, 0, 0, 1, 1, 1, 1, ...
row 6 = 1, 0, 0, 1, 1, 0, 1, 0, 1, 1, 0, 0, 1, 1, 1, 1, ...
row 5 = 1, 1, 0, 0, 1, 0, 1, 1, 1, 1, 0, 0, 1, 0, 1, 1, ...
row 4 = 1, 1, 0, 0, 1, 0, 1, 1, 1, 1, 0, 0, 1, 0, 1, 1, ...
row 3 = 1, 0, 1, 1, 1, 0, 1, 1, 1, 0, 1, 1, 1, 0, 1, 1, ...
row 2 = 1, 0, 1, 1, 1, 0, 1, 1, 1, 0, 1, 1, 1, 0, 1, 1, ...
row 1 = 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, ...
row 0 = 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, ...
The initial antidiagonals (starting in the bottom left corner) are:
[1]
[1, 1]
[1, 1, 1]
[1, 0, 1, 1]
[1, 0, 1, 1, 1]
[1, 1, 1, 1, 1, 1]
[1, 1, 0, 1, 1, 1, 1]
[1, 0, 0, 0, 1, 0, 1, 1]
[1, 0, 0, 0, 1, 0, 1, 1, 1]
[1, 1, 0, 1, 1, 0, 1, 1, 1, 1]
[1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1]
[1, 0, 1, 0, 1, 0, 1, 1, 1, 0, 1, 1]
[1, 0, 1, 0, 0, 0, 1, 1, 1, 0, 1, 1, 1]
