Square number. Square number 16 as sum of gnomons. In mathematics, a square number or perfect square is an integer that is the square of an integer; [ 1 ] in other words, it is the product of some integer with itself. For example, 9 is a square number, since it equals 32 and can be written as 3 × 3.

In mathematics, a square-free integer (or squarefree integer) is an integer which is divisible by no square number other than 1. That is, its prime factorization has exactly one factor for each prime that appears in it. For example, 10 = 2 ⋅ 5 is square-free, but 18 = 2 ⋅ 3 ⋅ 3 is not, because 18 is divisible by 9 = 32.
All square triangular numbers have the form , where is a convergent to the continued fraction expansion of , the square root of 2. [4]A. V. Sylwester gave a short proof that there are infinitely many square triangular numbers: If the th triangular number (+) is square, then so is the larger (+) th triangular number, since:
25 is the sum of the five consecutive single-digit odd natural numbers 1, 3, 5, 7, and 9. 25 is a centered octagonal number, [1] a centered square number, [2] a centered octahedral number, [3] and an automorphic number.
