• Numbers (with nonzero digits only) where A046810 increases.at n=18A046811
• Largest k > 1 such that (sum of digits of k^n)*(sum of digits of k^(n+1)) = k, or 0 if no such k exists.at n=13A130181
• Third left hand column of triangle A163940.at n=29A163943
• a(n) = n-1 for n <= 4, otherwise if n is even then a(n) = a(n-5)+2^(n/2), and if n is odd then a(n) = a(n-1)+2^((n-3)/2).at n=32A200310
