 OFFSET 1,2 COMMENTS Right border A144253 = A125274, the eigensequence of A078812: (1, 1, 3, 10, 42, 210, 1199,...). Row sums = A125274 shifted. Sum of row n terms = rightmost term of next row. LINKS FORMULA Eigensequence by rows, T(n,k) = A078812(n,k) * A125274(k). EXAMPLE First few rows of the triangle = 1; 2, 1; 3, 4, 3; 4, 10, 18, 10; 5, 20, 63, 80, 42; 6, 35, 168, 360, 420, 210; 7, 56, 378, 1200, 2310, 2520, 1199; ... Triangle A078812 begins: 1; 2, 1; 3, 4, 1; 4, 10, 6, 1; 5, 20, 21, 8, 1; ... Its eigensequence = A125274: (1, 1, 3, 10, 42, 210, 1199,...). Row 3 of triangle A144253 = termwise products of (4, 10, 6, 1) and (1, 1, 3, 10) = (4*1, 10*1, 6*3, 1*10). CROSSREFS A078812, Cf.
