COMMENT
|
Row sums = A007859: (1, 3, 5, 6, 6, 6, 7, 9, 11,...).
n-th row = (n+1) terms of an infinitely periodic cycle: (...1, 0, 0, 1, 2, 2, 1, 0, 0, 1, 2, 2, 1), shifting to the right one place for the next row

FORMULA
|
Construct an A010892 descrecendo triangle: (1; 1,1; 0,1,1; -1,0,1,1;...) and take partial sums starting from the right.
|
|
EXAMPLE
|
First few rows of the triangle =
1;
2, 1;
2, 2, 1;
1, 2, 2, 1;
0, 1, 2, 2, 1;
0, 0, 1, 2, 2, 1;
1, 0, 0, 1, 2, 2, 1;
2, 1, 0, 0, 1, 2, 2, 1;
2, 2, 1, 0, 0, 1, 2, 2, 1;
1, 2, 2, 1, 0, 0, 1, 2, 2, 1;
0, 1, 2, 2, 1, 0, 0, 1, 2, 2, 1;
...
Row 3 =(1, 2, 2, 1) = partial sums of (-1, 0, 1, 1).
