• G.f. satisfies A(x) = 1 + x*cycle_index(G,A(x)) where G = cyclic group of order 3 generated by (1,2,3)(4,5,6).at n=9A036726
• Integers y such that for some integer x we have uphi(x) = uphi(y) = x-y, where uphi(n) = A047994(n) is the unitary totient function: If n = Product p_i^e_i, uphi(n) = Product (p_i^e_i - 1).at n=31A067741
