• Define the sequence S(a(0),a(1)) by a(n+2) is the least integer such that a(n+2)/a(n+1) > a(n+1)/a(n) for n >= 0. This is S(5,45).at n=4A022022
• Absolute value of difference between counts of uninterrupted runs of 3 nonprimes in A093187 and A093188.at n=11A093399
• a = a(n) is such that the a-th prime p(a) is the least prime with digital sum equal to n, or a(n)=0 if no such prime exists.at n=46A104290
• Start with 1 and repeatedly reverse the digits and add 66 to get the next term.at n=9A118200
• Numbers n such that phi(phi(n)) + sigma(sigma(n)) is a 4th power.at n=20A172464
