• Numbers k such that k divides s(k), where s(1)=1, s(j) = s(j-1) + j*13^(j-1).at n=20A014953
• a(n) is the least k such that k and k+n are adjacent powerful numbers.at n=21A103954
• Monotonic ordering of set S generated by these rules: if x and y are in S then x^2+y^2+xy is in S, and 1 is in S.at n=19A192535
