The sixth one (oo/oo -m) is the symmetry group of a conventional … In solid state physics, the magnetic space groups, or Shubnikov groups, are the symmetry groups which classify the symmetries of a crystal both in space, and in a two-valued property such as electron spin. To represent such a property, each lattice point is colored black or white, and in addition to the usual three-dimensional symmetry operations, there is a so-called "antisymmetry" operation which turns all black lattice points white and all white lattice points black. Thus, the m…

Webception. The Curie symmetry principle has been greatly developed by Rosen, whose symmetry prin-ciple states that the symmetry group of the cause is a subgroup of the symmetry group of the effect [1-3]. Symmetry rules related to Rosen's symmetry principle are summarized in the last chapter, chapter 12, of this new book.
