%0 Journal Article %T Vertex-transitive maps on a torus %A O. Such %J ACTA MATHEMATICA UNIVERSITATIS COMENIANAE %D 2011 %I Acta Mathematica Universitatis Comenianae %X We examine FVT (free, vertex transitive) actions of wallpaper groups on semiregular tilings. By taking quotients by lattices we then obtain various families of FVT maps on a torus, and describe the presentations of groups acting on the torus. Altogether there are 29 families, 5 arising from the orientation preserving wallpaper groups and 2 from each of the remaining wallpaper groups. We prove that all vertex-transitive maps on torus admit an FVT map structure. %K torus %K wallpaper group %K vertex-transitive map %K Cayley map %K semiregular tiling %U http://www.iam.fmph.uniba.sk/amuc/_vol-80/_no_1/_such/such.pdf
