Integers which are perfect squares are rare; only about \frac1 {\sqrt {x}} x1 of the integers in the set \ { 1, 2, \ldots, x \} {1,2,…,x} are perfect squares. On the other hand, given an odd prime p p, integers that are squares modulo p p are relatively common. In fact, it turns out that exactly half of the integers ...
