In summary, inversion symmetry, also known as mirror symmetry, is a type of symmetry in which an object or system is unchanged when it is inverted or reflected. It is different from other types of symmetry because it involves a reflection or inversion rather than a rotation or translation. Examples of objects with inversion symmetry include crystals, molecules, and human faces. In science and technology, inversion symmetry is used for various purposes such as determining atomic structures and understanding properties of molecules. It is also possible for an object to have both inversion symmetry and other types of symmetry, but not all objects have inversion symmetry.
