OEIS Sequences

Numbers that are the sum of seven fourth powers in exactly eight ways. A345830

a(n) = a(n-1) + a(floor(n/2)) + a(ceiling(n/2)). A131205

a(n) = dot_product(1,2,...,n)*(3,4,...,n,1,2). A26037

G.f. satisfies: A(x) = Catalan(x + x² + x³*A(x)) where Catalan(x) = (1-sqrt(1-4·x))/(2x) is the g.f. of A000108. A162162

a(1)=2; thereafter a(n) = a(n-1) + gpf(a(n-1)) - 1, where gpf = greatest prime factor = A006530. A389408
