That would be 26 . . . its square is 676.
There are two smaller palindromic squares . . . 121 and 484 ... but they're the squares of
11 and 22 respectively, which are palindromic, so they flunk the question's specifications.
262 = 676

11 is a palindrome.11 squared (i.e., 11 times 11) is 121, which is also a palindrome.
4, which is the square of the prime number 2, is the smallest composite number.

112 = 121
26^2 = 676
The smallest square number qreater than 1 is 2. * * * * * 2 is not a perfect square number.
4 or 121

11 is a palindrome.11 squared (i.e., 11 times 11) is 121, which is also a palindrome.
If the number is one, then it is the smallest positive square.
4, which is the square of the prime number 2, is the smallest composite number.
The smallest perfect square is 121.
