• 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=31A324686
• a(n) = Sum_{k=1..n} k^3 * phi(k).at n=14A344526
