 OFFSET 0,10 COMMENTS Row sums = A011782: (1, 1, 2, 4, 8, 16, ...). Left border = A144157: (1, 0, 1, 1, 2, 3, 5, 8, ...). Sum of n-th row terms = rightmost term of next row. LINKS Table of n, a(n) for n=0..44. FORMULA Triangle read by rows, A * B. A = an infinite lower triangular decrescendo subsequences triangle with A144157: (1, 0, 1, 1, 2, 3, 5, 8, ...) in every column; and B = (A011782 * 0^(n-k)), 0 <= k <= n = (1; 0,1; 0,0,2; 0,0,0,4; 0,0,0,0,8; ...). EXAMPLE First few rows of the triangle: 1; 0, 1; 1, 0, 1; 1, 1, 0, 2; 2, 1, 1, 0, 4; 3, 2, 1, 2, 0, 8; 5, 3, 2, 2, 4, 0, 16; 8, 5, 3, 4, 4, 8, 0, 32; 13, 8, 5, 6, 8, 8, 16, 0, 64; ... Row 5 = (3, 2, 1, 2, 0, 8) = termwise product of (3, 2, 1, 1, 0, 1) and (1, 1, 1, 2, 4, 8) = (3*1, 2*1, 1*1, 1*2, 0*4, 1*8).
