 OFFSET 1,10 COMMENTS Row sums = A144023, the INVERT transform of the rabbit sequence, A005614. Left border = A005614. Sum of n-th row terms = rightmost term of next row. LINKS FORMULA Eigentriangle by rows, T(n,k) = A005614(n-k+1)*A144023(k-1). A005614 = the rabbit sequence, (1, 0, 1, 1, 0, 1, 0, 1,...) A144023(k-1) = A144023 shifted to (1, 1, 1, 2, 4, 6, 10, 17, 29,...). EXAMPLE First few rows of the triangle = 1; 0, 1; 1, 0, 1; 1, 1, 0, 2; 0, 1, 1, 0, 4; 1, 0, 1, 2, 0, 6; 0, 1, 0, 2, 4, 0, 10; 1, 0, 1, 0, 4, 6, 0, 17; 1, 1, 0, 2, 0, 6, 10, 0, 29; ...; Row 4 = (1, 1, 0, 2) = termwise product of (1, 1, 0, 1) and (1, 1, 1, 2); where (1, 1, 0, 1) = the first 4 terms of A005614 reversed. (1, 1, 1, 2) = the first 4 terms of shifted A144023. CROSSREFS A005614, Cf.
