It is shown how to enumerate such objects with a given finite automorphism group ?$G$?, how to represent them all as quotients of a single regular object ?$\mathcal{U}(G)$?, and how the outer automorphism group of ?$\Gamma$? acts on them. Examples constructed include kaleidoscopic maps with trinity symmetry</dc:description><dc:description xml:lang="sl">Regularne objekte v različnih kategorijah, kot so zemljevidi, hiperzemljevidi ali krovni prostori, lahko identificiramo z edinkami ?$N$? dane grupe ?$\Gamma$? , ki imajo grupo avtomorfizmov izomorfno ?$\Gamma / N$?. Pokažemo, kako prešteti takšne objekte z dano končno grupo avtomorfizmov ?$G$?, kako jih vse predstaviti kot kvociente enega samega regularnega objekta ?$\mathcal{U}(G)$?, in kako grupa zunanjih avtomorfizmov grupe ?$\Gamma$? deluje na njih.
