 OFFSET 2,3 COMMENTS A181631 = number of leading 1's in Fibonacci Maximal notation. This notation uses headings: (...5, 3, 2, 1); and fills in entries starting from the right, as opposed to the left. For example n=8 = 1011 = (5 + 2 + 1) as opposed to Minimal notation which would be (1100) = (5 + 3). Conjectured row sums = A023610: (1, 3, 7, 15, 30, 58, ...). Is this the same as A112310? - R. J. Mathar, Nov 03 2010 Contribution from Gary W. Adamson, Nov 03 2010: (Start) The next row of 13 terms = (3, 4, 4, 5, 6, 4, 4, 5, 4, 5, 5, 5, 6), sum = 58. (End) LINKS Table of n, a(n) for n=2..20. FORMULA Count numbers of 1's in Fibonacci Maximal notation for n. EXAMPLE First few terms of the triangle: 1; 1, 2; 2, 2, 3; 2, 3, 3, 3, 4; 3, 3, 4, 3, 4, 4, 4, 5; ... Example: 10 in Fibonacci Maximal = 1110, having three 1's, so a(10) = 3. CROSSREFS Cf. A023610, A181631.
