• a(n) = (n+6)*(n+1)*(n^2 + 7*n + 16)/4.at n=18A168538
• Number of compositions of n with difference -5 between the number of odd parts and the number of even parts, both counted without multiplicity.at n=10A242836
• Starting at n, a(n) is the number of times we travel to a position already visited 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=32A324674
