Geometry of Symmetry Plane
Points on a plane in spacetime are not only affine grid points, but also holding symmetry plane condition with indistinguishable back and front surfaces. This symmetry of a plane gives rise not only to Euclidean geometry in a space~space type plane, but also to relativity principle in a space~time type plane.@See my paper [PDF] or conference paper description [Description].
