For d = 2, triangular k-reptiles exist for all k of the form a^2, 3a^2 or a^2+b^2 and they have been completely characterized by Snover, Waiveris, and Williams. On the other hand, the only k-reptile simplices that are known for d ≥ 3, have k = m^d, where m is a positive integer. We substantially simplify the proof by Matoušek and the second author that for d = 3, k-reptile tetrahedra can exist only for k = m^3. We then prove a weaker analogue of this result for d = 4 by showing that four-dimensional k-reptile simplices can exist only for k = m^2.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2020-07-14T12:47:47Z","type":"journal_article","publisher":"International Press","day":"14","issue":"3","language":[{"iso":"eng"}],"year":"2017","publication_identifier":{"issn":["10778926"]},"volume":24,"date_created":"2018-12-11T11:48:00Z","date_updated":"2021-01-12T08:11:28Z","file":[{"creator":"system","access_level":"open_access","date_created":"2018-12-12T10:14:25Z","date_updated":"2020-07-14T12:47:47Z","relation":"main_file","file_name":"IST-2018-984-v1+1_Patakova_on_the_nonexistence_of_k-reptile_simplices_in_R_3_and_R_4_2017.pdf","file_size":544042,"checksum":"a431e573e31df13bc0f66de3061006ec","content_type":"application/pdf","file_id":"5077"}],"month":"07","publication_status":"published","oa_version":"Submitted Version","_id":"701","status":"public","department":[{"_id":"UlWa"}],"publication":"The Electronic Journal of Combinatorics","author":[{"full_name":"Kynčl, Jan","last_name":"Kynčl","first_name":"Jan"},{"first_name":"Zuzana","last_name":"Patakova","full_name":"Patakova, Zuzana","id":"48B57058-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3975-1683"}],"page":"1-44"}
