- G.f. satisfies: A(x/A(x)) = 1 + x*A(x)^3.at n=6A145347
- Given a set of positive integers A={1,2,...,n-1,n}, n>=2. Take subsets of A of the form {1,...,n} so only subsets containing numbers 1 and n are allowed. Then a(1)=1 and a(n) is the number of subsets where arithmetic mean of the subset is an integer.at n=19A147980
