Appears in sequences

• Arises from a social choice theory problem. Sequence is a transformation of the number of non-transitive non-quasitransitive acyclic distinct profiles with 3 alternatives and strict individual preferences.at n=6A082678
• a(n) = numerator of any non-diagonal entry of the matrix A^n, where A is described in the Comments lines.at n=7A093378
• Integer areas of integer-sided triangles where two sides are of square length.at n=35A232461
• Constant term in the expansion of (Sum_{k=0..n} k*(x^k + x^(-k)))^3.at n=15A303916
• a(n) = Sum_{k=0..floor((n-1)/3)} 2^k * |Stirling1(n,3*k+1)|.at n=9A357832
• Triangular array T(n, k) read by rows: polynomials for the series expansion of the iterated function F^{t}(x) = Sum_{n>=0} (1/x)^(2*n-1)*P_n(t)/n! with F^{1}(x) = (x + sqrt(x^2 + 4))/2 and F^{2}(x) = F^{1}(F^{1}(x)). Row n of the triangle give the coefficients of the polynomial P_n(t).at n=33A390822
