 OFFSET 1,2 COMMENTS Row sums = A023610: (1, 3, 7, 15, 30, 58,...). LINKS FORMULA The triangle as an infinite lower triangular matrix = A * B. A = a Fibonacci subsequences decrescendo triangle: (1; 2,1; 3,2,1; 5,3,2,1;...) and B = A127647, an infinite lower triangular matrix with the Fibonacci sequence as the main diagonal and the rest zeros. EXAMPLE First few rows of the triangle = 1; 2, 1; 3, 2, 2; 5, 3, 4, 3; 8, 5, 6, 6, 5; 13, 8, 10, 9, 10, 8; 21, 13, 16, 15, 15, 16, 13; 34, 21, 26, 24, 25, 24, 26, 21; ... Row 4 = (5, 3, 4, 3) = termwise products of (5, 3, 2, 1) and (1, 1, 2, 3).
