Is the symmetry group always about affine transformations? In some context symmetries are motions (or isometries) rather than all affine transformations. More generally, isomorphisms of a given structure (of any kind) are often called symmetries. --[[User:Boris Tsirelson|Boris Tsirelson]] 07:18, 16 December 2010 (UTC) | |||
