 OFFSET 0,6 LINKS Seiichi Manyama, Antidiagonals n = 0..139, flattened FORMULA A(0,k) = 1, A(1,k) = A(2,k) = ... = A(k,k) = 0 and A(n,k) = (-1)^(k+1) * Sum_{i=k..n-1} (-1)^i*(i+1)!*binomial(n-1,i)*A(n-1-i,k) for n > k. EXAMPLE Square array begins:       1,   1,    1,   1, ...      -1,   0,    0,   0, ...       3,  -2,    0,   0, ...     -13,   6,   -6,   0, ...      73, -12,   24, -24, ...    -501,   0, -120, 120, ... CROSSREFS Columns k=0..2 give A293125, A293122, A293123. Rows n=0..1 give A000012, (-1)*A000007. Main diagonal gives A000007. A(n,n-1) gives (-1)*A000142(n). Cf. A293053, A293119, A293133.
