Row sums = A144181: (1, 1, 3, 9, 11, 17, 35,...).

Left border = A118434: (1, 0, 2, 4, -4, 0, -8,...); (i.e. row sums of the self-inverse triangle A118433).

Triangle A144183 = partial sums starting from the right of A144182.

Sum of n-th row terms = rightmost term of next row.

Triangle read by rows, T(n,k) = A118434(n-k)*A144181(k-1); where A144181(k-1) = A144181 shifted to (1, 1, 1, 3, 9, 11, 17, 35, 57, 91, 161,...).

First few rows of the triangle are:

1;

0, 1;

2, 0, 1;

4, 2, 0, 3;

-4, 4, 2, 0, 9;

0, -4, 4, 6, 0, 11;

-16, -8, 0, -12, 36, 22, 0, 35;

...

row 3 = (4, 2, 0, 3) = termwise products of (4, 2, 0, 1) and (1, 1, 1, 3) = (4*1, 2*1, 0*1, 1*3).
