We provide criteria for determining when a self-similar group of finite type is finite, level-transitive, or topologically finitely generated. Using these criteria and GAP computations we show that for the binary alphabet there is no infinite topologically finitely generated self-similar group given by patterns of depth $3$, and there are $32$ such groups for depth $4$.", "revisions": [ { "version": "v1", "updated": "2014-08-30T15:34:36.000Z" } ], "analyses": { "subjects": [ "20F65", "20F05", "20E08" ], "keywords": [ "finite type", "finite generation", "finitely generated self-similar group", "vertex act", "infinite topologically finitely generated self-similar" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
