"WebAug 28, 2016 · 1 Answer. There are only finitely many base- 2 palindromes whose square is also a base- 2 palindrome. Namely, the trivial 0 (if one counts that as a palindrome), 1, and the not-quite-trivial 3 = 112. To see that, let's first look at numbers with few bits set. There's only one number with no bits set, 0. " - Palindromic squares 回文平方数
