• Expansion of tan(log(1+x)^2).at n=7A009655
• Triangle read by rows: T(0,0)=1; for n>=1 T(n,k) is the coefficient of x^k in the monic characteristic polynomial of the n X n band matrix with main diagonal 2,3,3,..., subdiagonal -3,-3,-3,..., sub-subdiagonal 1,1,1,... and superdiagonal -1,-1,-1,... (0<=k<=n).at n=49A124019
• Triangle read by rows: alternating binomial coefficients with signs.at n=39A156290
• The n-th term of the n-th Dirichlet self-convolution equals n^2.at n=41A163591
• Array: row n shows the coefficients of the characteristic polynomial of the n-th principal submatrix of (f(i,j)), where f(i,1)=f(1,j)=1, f(i,i)= i; f(i,j)=0 otherwise; as in A204179.at n=45A204180
• Irregular triangle read by rows: Coefficients of Schick's polynomials P(n, y^2), for n >= 1.at n=17A327923
• Expansion of e.g.f. -log(1 - x) * exp(-3*x).at n=8A346398
• a(n) is the smallest error in trying to solve n^5 = x^5 + y^5: for each n from 2 on, find positive integers x and y, x <= y < n such that |n^5 - x^5 - y^5| is minimal and let a(n) = n^5 - x^5 - y^5. In case of a tie, choose the solution with smallest y.at n=25A369855
