 OFFSET 0,2 COMMENTS Right border = A026150: (1, 1, 4, 10, 28, 76, 208, 568,...). Row sums = (1, 4, 10, 28, 76,...) = INVERT transform of (1, 3, 3, 3,...). Sum of n-th row terms = rightmost term of next row. LINKS FORMULA Eigentriangle by rows, n terms of (3 * A026150) followed by A026150(n). EXAMPLE First few rows of the triangle = 1; 3, 1; 3, 3, 4; 3, 3, 12, 10; 3, 3, 12, 30, 28; 3, 3, 12, 30, 84, 76; 3, 3, 12, 30, 84, 228, 208; ...
