- Palindromes in which the sum of the internal digits = the sum of the external digits.at n=28A088285
- Zeroless numbers n such that n and n - (product of digits of n) are both palindromes.at n=37A229761
- For every positive integer m, let u(m) = (d(1),d(2),...,d(k)) be the unitary divisors of m. The sequence (a(n)) consists of integers of the form d(k)/d(1) + d(k-1)/d(2) + ... + d(k)/d(1).at n=17A229999
- Palindromes of the form 4n + 1 that are divisible by 5.at n=27A256704
- Triangle read by rows: T(n,k) = 4*T(n-1,k-1) + T(n,k-1) with T(2*m,0) = 0 and T(2*m+1,0) = 5^m.at n=50A292466
