3.7.37. Border

$𝚙𝚎𝚛𝚒𝚘𝚍$ .

A constraint that can be related to the notion of border, which we define now. Given a sequence $s = u r v$ , $r$ is a prefix of $s$ when $u$ is empty, $r$ is a suffix of $s$ when $v$ is empty, $r$ is a proper factor of $s$ when $r \neq s$ . A border of a non-empty sequence $s$ is a proper factor of $s$ , which is both a prefix and a suffix of $s$ . We have that the smallest period of a sequence $s$ is equal to the size of $s$ minus the length of the longest border of $s$ .
