• The Wiener index of the fullerenyl anion G[n]C[60], defined pictorially in the Arezoomand reference (see Fig. 5).at n=2A221016
• a(n) = floor(5^n/4^(n-1)).at n=43A241203
• a(0) = 0, and for n > 0, (a(n)) gives the indices n for which d(n) > d(k) for k < n, where d is the difference sequence of (cos k + sin k).at n=33A299639
