Construction sequences are a general method of building symbolic shifts that capture cut-and-stack constructions and are general enough to give symbolic representations of Anosov-Katok diffeomorphisms. We show here that any finite entropy system that has an odometer factor can be represented as a special class of construction sequences, the odometer based construction sequences which correspond to those cut-and-stack constructions that do not use spacers. We also show that any additional property called the "small…
