• Base-2 digits are, in order, the first n terms of the periodic sequence with initial period [1,1,0].at n=22A033129
• Triangle read by rows: row n contains n terms of the arithmetic progression having first term 1 and common difference 2[n^(n-1)-1]/(n-1).at n=34A111568
• a(n) = a(n-1) + 2^(A007494(n-1)).at n=14A113835
