- Non-palindromic squares which when written backwards remain square (and still have the same number of digits).at n=27A035090
- Squares k^2 such that reverse(k)^2 = reverse(k^2), excluding squares of palindromes.at n=25A064021
- Smallest square containing all the digits of numbers from 1 to n. For a(10) and higher, all duplicated digits must be in the term (for example a(10) has two 1's).at n=5A069600
- Perfect squares with property that their digit reversal is a larger perfect square.at n=18A156316
- Number of (n+2) X (5+2) 0..1 arrays with no 3 x 3 subblock diagonal sum less than the antidiagonal sum or central row sum less than the central column sum.at n=29A258891
