Appears in sequences

• Let f(n) = exp(Pi*sqrt(n)); sequence gives numbers n such that f(n) - floor(f(n)) < 1/10^4.at n=31A127029
• G.f. satisfies: A(x) = G(x*A(x)) where G(x) = A(x/G(x)) = Sum_{n>=0} x^(n(n+1)/2)*(1+x)^n.at n=12A172405
• Number of unlabeled nonseparable (or 2-connected) multigraphs with n edges, loops allowed.at n=12A360881
