• a(n) = A023194 - A062700(n). Negative values of A071166(m) = m-A006530(A000203(m)) differences. In these cases m is square number from A023194.at n=43A071167
• Nearest integer to 1 / Sum_{p prime, 2^n < p <= 2^(n+1)} (Kronecker(-1/p)/p).at n=13A166510
• G.f.: q-Cosh(x,q)^2 - q-Sinh(x,q)^2 at q=-x.at n=50A198199
• Array: row n shows the coefficients of the characteristic polynomial of the n-th principal submatrix of the symmetric matrix A202670 based on A000290 (the squares); by antidiagonals.at n=36A202671
• G.f. (1-x) * Sum_{n>=0} x^n * (1 + x^n)^n / (1 + x^(n+1))^(n+1).at n=35A354247
