• G.f. satisfies: A(x) = x^2/(1-x) + A(A(x)).at n=15A213906
• Starting at n, a(n) is the number of moves made away from zero according to the following rules. On the k-th step (k=1,2,3,...) move a distance of k in the direction of zero. If the number landed on has been landed on before, move a distance of k away from zero instead.at n=34A324663
