• a(n) = Sum_{k=0..n} abs(stirling1(n,k))*stirling2(n+1,k+1)*k!^2.at n=5A192566
• Starting at n, a(n) is the number of times we move away from zero from a negative position 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.at n=17A324686
