• a(n) = 2*n^4 - floor(2^(1/4)*n)^4.at n=31A257854
• G.f. A(x,y) satisfies: Sum_{n=-oo...+oo} (x^n + y)^n = exp( (1-y) * A(x,y) ) / (1-y), where A(x,y) = Sum_{n>=1} x^n/n * Sum{k=0..n-1} T(n,k)*y^k, written here as a flattened triangle of coefficients T(n,k) read by rows.at n=42A321600
• Expansion of H(x)*(1+x^5)/(1-x^2-x^3-x^4) where H(x) = g.f. for A249665.at n=18A337654
