Abstract

Regular maps on linear fractional groups PSL(2,q)PSL(2,q) and PGL(2,qPGL(2,q) have been studied for many years and the theory is well-developed, including generating sets for the asscoiated groups. This paper studies the properties of self-duality, self-Petrie-duality and M\"obius regularity in this context, providing necessary and sufficient conditions for each case. We also address the special case for regular maps of type (5,5). The final section includes an enumeration of the PSL(2,q)PSL(2,q) maps for q81q\le81 and a list of all the PSL(2,q)PSL(2,q) maps which have any of these special properties for q49q\le49.
