Non-contracting groups generated by (3,2)-automata

We add to the classification of groups generated by 3-state automata over a 2-letter alphabet given by Bondarenko \( et \ al.\), by showing that a number of the groups in the classification are non-contracting. We show that the criterion we use to prove a self-similar action is non-contracting also...

Description
Summary:We add to the classification of groups generated by 3-state automata over a 2-letter alphabet given by Bondarenko \( et \ al.\), by showing that a number of the groups in the classification are non-contracting. We show that the criterion we use to prove a self-similar action is non-contracting also implies that the associated self-similarity graph introduced by Nekrashevych is non-hyperbolic.
