Özet

© 2022, The Author(s), under exclusive licence to Springer Japan KK, part of Springer Nature.Let N= 2 α3 β. The normalizer Γ B(N) of Γ (N) in PSL(2 , R) is the triangle group (2 , 4 , ∞) for α= 1 , 3 , 5 , 7 ; β= 0 , 2 and the triangle group (2 , 6 , ∞) for α= 0 , 2 , 4 , 6 ; β= 1 , 3. In this paper we examine relationship between the normalizer and the regular maps. We define a family of subgroups of the normalizer and then we study maps with quadrilateral and hexagonal faces using these subgroups and calculating the associated arithmetic structure.
