Antidiagonal sums of table A162424. A162428

G.f.: ∏_k>=1 (1 - x^k)^-k⁷. A23876

Numbers k such that k and 5·k, taken together, are pandigital. A115925

Row n=4 of A144048. A283456

a(n) is the number of different graphs drawn in the following way: you decide for each number k <= n on a pair of positive numbers (x(k),y(k)) such that x(k)+y(k)=k; you draw n points numbered 1 to n; draw two arrows from n, one to x(n) and one to y(n); draw two arrows from each k already reached by an arrow, one to x(k) and one to y(k). The process stops when 1 is the only point reached by an arrow without any arrow leaving it; you can also erase the isolated points. A58050

Numbers that are divisible by the total number of 1's in both the Zeckendorf and the dual Zeckendorf representations of all their divisors (A300837 and A333618). A333621
