Formally, an infinite sequence of words ''w''(''n'') is locally catenative if, for some positive integers ''k'' and ''i''₁,...''i''_''k'':

:<math>w(n)=w(n-i_1)w(n-i_2)...\ldots w(n-i_k) \text{ for } n \ge \max(\{i_1, ...\ldots, i_k)\} \, .</math>

Some authors use a slightly different definition in which encodings of previous words are allowed in the concatenation.<ref>{{cite book
