"WebLet us call Wheeler languages this class. First of all, Wheeler languages are clearly regular since, by definition, they are accepted by finite state automata. Moreover, all finite languages are Wheeler because they can be recognized by a tree-shaped automaton, which (as seen in Section 3.5) is always prefix-sortable.
