• a(n) = 121*n^2 + 2*n.at n=13A181679
• 7-step Fibonacci sequence starting with (0,1,0,0,0,0,0).at n=22A251714
• Number of permutations p of [n] whose absolute displacements |p(i)-i| are triangular numbers.at n=11A324374
• a(n) is the number of multisets of integers that are possible to reach by starting with n occurrences of 0 and by splitting. Splitting is taking 2 occurrences of the same integer and incrementing one of them by 1 and decrementing the other occurrence by 1.at n=14A347913
