• a(n) is the concatenation of n with n^3.at n=19A061086
• Partial sums of floor(Fibonacci(n)/4).at n=28A179006
• a(n) = Catalan(n) - n.at n=12A246604
• A246604 (Catalan(n)-n) with initial terms 1,0,0,2 changed to 1,1,1,3.at n=12A289615
• A246604 (Catalan(n)-n) with initial terms 1,0,0,2,10 changed to 1,1,1,2,11.at n=12A289616
• Take a number z of x digits and consider any concatenation z = concat(y_1, y_2, ..., y_i) where y_1, y_2, ..., y_i have the same number of digits. Then be g(z) the product of the sums y_1 + y_2 + ... + y_i for all those concatenations. Sequence lists numbers z such that g(g(z)) = z. (See example.)at n=2A317628
• Triangle read by rows: T(n,k) is k-th entry of the toric g-vector of the n-dimensional associahedron, 0 <= k <= floor(n/2).at n=37A390883
