• Define the generalized Pisot sequence T(a(0),a(1)) by: a(n+2) is the greatest integer such that a(n+2)/a(n+1) < a(n+1)/a(n). This is T(8,16).at n=15A018922
• Expansion of 1/(1-2*x+x^5).at n=18A107066
• Numbers k such that k and k^2 use only the digits 1, 2, 5, 6 and 8.at n=36A137005
• List of different composites in Pascal-like triangles with index of asymmetry y = 3 and index of obliqueness z = 0 or z = 1.at n=42A141069
• Number of columns with an odd sum in all 2-compositions of n. A 2-composition of n is a nonnegative matrix with two rows, such that each column has at least one nonzero entry and whose entries sum up to n.at n=9A181326
