In this paper we generalise Singerman’s results on triangle group inclusions to the broader class of generalised quadrangle groups, that is, Fuchsian groups with signature of genus 0 and generated by three or four elliptic generators. For any possible inclusion P < Q we also give the number of non-conjugate subgroups of Q isomorphic to P. Kategória publikačnej činnosti ADM Číslo archívnej kópie 40854 Katal.org.

In this paper we describe the first two infinite families of Archimedean maps on higher genera which we call "generalized" prisms and "generalized" antiprisms.

The graph X is said to be 1/2-arc-transitive if Aut X is 1/2-arc-transitive. The interplay of two different concepts, maps and hypermaps on one side and 1/2-arc-transitive group actions on graphs on the other, is investigated. The correspondence between regular maps and 1/2-arc-transitive group actions on graphs of valency 4 given via the well known concept of medial graphs (European J. Combin. 19 (1998) 345) is generalised. Any orientably regular hypermap R gives rise to a uniquely determined medial map whose underlying graph Y admits a 1/2-arc-transitive group action of the automorphism group G of the original hypermap R. Moreover, the vertex stabiliser of the action of G on Y is cyclic. On the other hand, given graph X and G less than or equal to Ant X acting 1/2-arc-transitively with a cyclic vertex stabiliser, we can construct an orientably regular hyperma Kategória publikačnej činnosti ADE Číslo archívnej kópie 28527 Kategória ohlasu WANG, Xiuyun - FENG, Yan-Quan.
