 OFFSET 0,2 COMMENTS 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 LINKS FORMULA Construct an A010892 decrescendo 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). CROSSREFS A010892, Cf.
