Abstract:We construct and study a family of 3-generated groups $$\mathcal{D}_w$$ parametrized by infinite binary sequences w. We show that two groups of the family are isomorphic if and only if the sequences are cofinal and that two groups cannot be distinguished by finite sets of relations. We show a connection of the family with 2-dimensional holomorphic dynamics.
Keywords:Space of groups  Self-Similar groups  Iterated monodromy groups
