Abstract
The present paper is devoted to the further development of the discrete theory of Riemann surfaces. This theory considers finite graphs as analogous of Riemann surfaces and branched coverings of graphs as holomorphic maps. The main object of investigation are automorphism groups of graphs acting freely on the set of arcs and the corresponding regular coverings.
