The Kolakoski sequence is an infinite sequence of integers that is defined recursively. It is notable because it is self-generating and consists only of the integers 1 and 2. The sequence begins with 1 and is constructed by reading the lengths of groups of 1s and 2s as specified by the terms of the sequence itself. The construction process goes as follows: 1. Start with the initial term: \\( 1 \\).
