• Expansion of -3*x/(1 - 5*x + 3*x^2).at n=6A106732
• Array: row n shows the coefficients of the characteristic polynomial of the n-th principal submatrix of min{i-j+1,j-i+1} (A203994).at n=39A203995
• The j-invariants in A032354 are perfect cubes, except for two terms that have an extra factor of 2 or 3. Ignore these two extra factors and take the cube roots.at n=11A267195
• Expansion of Product_{k>=1} ((1 - x)^k - x^k)/((1 - x)^k + x^k).at n=15A307520
• Triangle read by rows: T(0,0) = 1; T(n,k) = - T(n-1,k) - 2 T(n-3,k-1) for k = 0..floor(n/3); T(n,k)=0 for n or k < 0.at n=74A317505
• Consider the e.g.f. B(x,y) = Sum_{n>=0} Sum_{k=0..floor(n/2)} T(n,k) * x^(2*n-2*k) * y^(2*k) / (2*n)! and related functions A(x,y) and C(x,y), as defined in the Formula section. Sequence gives the triangular array of coefficients T(n,k) (n>=0, 0<=k<=floor(n/2)) of B(x,y).at n=13A326798
• The sixth moments of the alternated squared binomial coefficients; a(n) = Sum_{m=0..n} (-1)^m*m^6*binomial(n, m)^2.at n=4A329521
• a(n) is the real cube root of the value of the j-function for the n-th Heegner number A003173(n).at n=7A357211
• Table read by rows. T(n, k) = [z^k] LommelR(n, n, 1/z) where LommelR are the Lommel polynomials.at n=38A369117
