%N Square array A(n,k), n>=0, k>=0, read by antidiagonals, where column k is the expansion of Product_{j>=1} (1-x^j)^(j*k) in powers of x.

%H Seiichi Manyama, <a href="/A276554/b276554.txt">Antidiagonals n = 0..139, flattened</a>

%F G.f. of column k: Product_{j>=1} (1-x^j)^(j*k).

%e Square array begins:

%e 1, 1, 1, 1, 1, ...

%e 0, -1, -2, -3, -4, ...

%e 0, -2, -3, -3, -2, ...

%e 0, -1, 2, 8, 16, ...
