Steinke, Günter F.2015-10-122015-10-1219930110-537Xhttp://hdl.handle.net/10092/11139This paper concerns 4-dimensional (topological locally compact connected) Minkowski planes that admit a 7-dimensional automorphism group 𝚺. It is shown that such a plane is either classical or has a distinguished point that is fixed by the connected component of 𝚺 and that the derived affine plane at this point is a 4-dimensional translation plane with a 7-dimensional collineation group.enCopyright Günter F.
