Automorphism groups of certain Enriques surfaces

The file AutEnrVol.pdf is the preprint: S. Brandhorst, I. Shimada: Automorphism groups of certain Enriques surfaces. The data in compdata.zip is the computation data that are used to obtain the main results of the preprint. AutEnrVolCompData.pdf is the explanation of the data in compdata.zip. EllFibs.pdf is the full table of elliptic fibrations of $(\tau, \taubar)$-generic Enriques surfaces in pdf format. A part of this table is given in AutEnrVol.pdf.
