N. J. A. Sloane, The Even Conant Lattice (The grid points (m,n) are labeled with pairs v(m,n), h(m,n).)
EXAMPLE
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, 1, 1, 0, 1, 1, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, ...
row 6 = 1, 1, 1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 1, 1, 0, 0, ...
row 5 = 1, 0, 0, 0, 1, 1, 0, 1, 0, 1, 1, 1, 0, 0, 1, 0, ...
row 4 = 1, 1, 1, 1, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 0, ...
row 3 = 1, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 1, 0, 0, 1, 0, ...
row 2 = 1, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 0, ...
row 1 = 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, ...
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, 0, 1]
[1, 1, 1, 1]
[1, 1, 0, 0, 1]
[1, 1, 0, 0, 1, 1]
[1, 0, 1, 1, 1, 0, 1]
[1, 1, 0, 1, 0, 1, 1, 1]
[1, 1, 1, 0, 0, 0, 0, 0, 1]
[1, 1, 1, 1, 1, 0, 1, 0, 1, 1]
[1, 0, 1, 0, 0, 1, 0, 0, 1, 0, 1]
[1, 1, 1, 1, 1, 0, 0, 0, 1, 1, 1, 1]
[1, 1, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0, 1]
