OEIS Sequences

a(n) is the number of reducible monic quintic polynomials (x⁵ + r·x⁴ + s·x³ + t·x² + u·x + v) with integer coefficients bounded by naïve height n (abs(r), abs(s), abs(t), abs(u), abs(v) <= n). A358400

Array read by ascending antidiagonals: A(n, k) = n! * [xⁿ] exp((k-1)*x)*(k·cosh(sqrt(k)*x) + sqrt(k)*sinh(sqrt(k)*x))/k, with 1 <= k <= n. A366858
