EXAMPLE

First few rows of the triangle =
1;
5, 3;
15, 11, 6;
34, 27, 19, 10;
65, 54, 42, 29, 15;
111, 95, 78, 60, 41, 21;
175, 153, 130, 106, 81, 55, 28;
260, 231, 201, 170, 138, 105, 71, 36;
369, 332, 294, 255, 215, 174, 132, 89, 45;
505, 459, 412, 364, 315, 265, 214, 162, 109, 55;
671, 615, 558, 500, 441, 381, 320, 258, 195, 131, 66;
...
Example: Row 3 = (15, 11 6) since row 3 of triangle A000027 = (4, 5, 6);
then taking partial sums from the right.
