• Scaled array A078740 ((3,2)-Stirling2).at n=43A090452
• Numbers n such that 6*10^n + 8*R_n + 1 is prime, where R_n = 11...1 is the repunit (A002275) of length n.at n=8A103047
• Base-10 numbers k such that k can be written as k = A * B and R(k) = R(A) * R(B) in six or more bases, from base 2 to base 10, and where R(k), the digit reversal of k, is read as a number in the same base.at n=2A346219
