An Archimedean map on the torus is called almost regular if it has as few flag orbits as possible for its type; for example, a map of type ?$(4.8^2)$? is called almost regular if it has exactly three flag orbits. Given a map of a certain type, we will consider other more symmetric maps that cover it. In this paper, we prove that each Archimedean toroidal map has a unique minimal almost regular cover. By using the Gaussian and Eisenstein integers, along with previous results regarding equivelar maps on the torus, we construct these minimal almost regular covers explicitly"},{"@xml:lang":"sl","#text":"Grupa avtomorfizmov zemljevida deluje naravno na njegovih praporih (trojicah incidentnih vozlišč, povezav in lic).

Za dani zemljevid danega tipa bomo obravnavali druge, bolj simetrične zemljevide, ki so njegovi krovi. V članku dokažemo, da ima vsak arhimedski torusni zemljevid en sam minimalen skoraj regularen krov. Z uporabo Gaussovih in Eisensteinovih celih števil, skupaj s predhodnimi rezultati, ki se nanašajo na ekvivelarne zemljevide na torusu, eksplicitno konstruiramo te minimalne skoraj regularne krove"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-NU82PBVA","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-NU82PBVA"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-NU82PBVA/7bcedb96-1f8e-4765-b1c4-53ea4cb40dc0/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza na Primorskem, Fakulteta za naravoslovje, matematiko in informacijske tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-NU82PBVA/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-NU82PBVA"}}}}
