• Number of ON cells at n-th stage of three-dimensional version of the cellular automaton A160410, using cubes.at n=22A160428
• Number of "ON" cubic cells at n-th stage in simple 3-dimensional cellular automaton: a(n) = A160428(n)/8.at n=44A161342
• Triangle read by rows: T(n,k) is the number of 2-compositions of n having k columns with an odd sum (0<=k<=n). A 2-composition of n is a nonnegative matrix with two rows, such that each column has at least one nonzero entry and whose entries sum up to n.at n=61A181308
