• Palindromic even lucky numbers.at n=38A045960
• Palindromic even squarefree numbers with an even number of distinct prime factors.at n=28A075811
• Palindromic even numbers with exactly 2 prime factors (counted with multiplicity). Equivalently, palindromic numbers of the form 2*p with p prime.at n=20A075813
• Numbers k such that k = x^2 + y^2 where x is the least primitive root of k. k is the first such number with x increasing in the sequence, x can be found in A082843.at n=7A082842
