It preserves the property of being semi-symmetric, and can be used to construct every semi-symmetric 4-regular graph that contains a pair of twin vertices. We show that (regardless of symmetry) subdivided doubles have another curious property: each of their many Hamiltonian cycles is complementary to another Hamiltonian cycle</dc:description><dc:description xml:lang="sl">Konstrukcijo subdividiranega dvojnika na 4-regularnih grafih sta Potočnik in Wilson uporabila pri raziskovanju polsimetričnih grafov (povezavno tranzitivnih, vendar ne vozliščno tranzitivnih grafov), z njo pa je mogoče konstruirati vsak polsimetričen 4-regularen graf, ki vsebuje par dvojnih vozlišč. Pokažemo, da imajo subdividirani dvojniki, ne glede na simetrijo, še eno zanimivo lastnost: imajo eksponentno mnogo Hamiltonovih ciklov, pri čemer je vsak izmed njih komplementaren nekemu drugemu Hamiltonovemu ciklu</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-MZVGZQGH"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-MZVGZQGH" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-MZVGZQGH/10d903dc-1f75-489a-9a95-71f4b5904b02/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza na Primorskem, Fakulteta za naravoslovje, matematiko in informacijske tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-MZVGZQGH/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-MZVGZQGH" /></ore:Aggregation></rdf:RDF>
