FORMULA
EXAMPLE
First few rows of the triangle =
1;
1, 1;
0, 1, 2;
-1, 0, 2, 3;
-1, -1, 0, 3, 4;
0, -1, -2, 0, 4, 5;
1, 0, -2, -3, 0, 5, 6;
1, 1, 0, -3, -4, 0, 6, 7;
0, 1, 2, 0, -4, -5, 0, 7, 8;
-1, 0, 2, 3, 0, -5, -6, 0, 8, 9;
-1, -1, 0, 3, 4, -6, -7, 0, 9, 10;
0, -1, -2, 0, 4, 5, 0, -7, -8, 0, 10, 11;
1, 0, -2, -3, 0, 5, 6, 0, -8, -9, 0, 11, 12;
...
Example: row 3 = (-1, 0, 3, 4) = termwise product of (-1, 0, 1, 1) and (1, 2, 3, 4) = (-1*1, 0*2, 1*3, 1*4). (-1, 0, 1, 1) = first 4 terms of A010892 reversed.
