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. A202671

Expansion of ∏_k>=1 ((1 - x^k)/(1 + x^k))^σ(k). A320971

G.f. satisfies: A(x) = exp( ∑_n>=1 xⁿ*A(x)ⁿ/n * ∑_k=0..2·n A084606(n,k)² * x^k * A(x)^2·k ), where A084606(n,k) = [x^k] (1 + 2·x + 2·x²)ⁿ. A218298
