WebThe magnetic space groups can be placed into three categories. First, the 230 colorless groups contain only spatial symmetry, and correspond to the crystallographic space groups. Then there are 230 grey groups, which are invariant under antisymmetry. Finally are the 1191 black-white groups, which contain the more complex symmetries. WebMar 24, 2024 · The crystallographic point groups are the point groups in which translational periodicity is required (the so-called crystallography restriction ). There are 32 such groups, summarized in the following table …

http://img.chem.ucl.ac.uk/sgp/LARGE/sgp.htm In crystallography, space groups are also called the crystallographic or Fedorov groups, and represent a description of the symmetry of the crystal. A definitive source regarding 3-dimensional space groups is the International Tables for Crystallography Hahn (2002) . History [ edit] See more In mathematics, physics and chemistry, a space group is the symmetry group of an object in space, usually in three dimensions. The elements of a space group (its symmetry operations) are the rigid transformations of … See more The space groups in three dimensions are made from combinations of the 32 crystallographic point groups with the 14 Bravais lattices, each of the latter belonging to one of 7 lattice systems. What this means is that the action of any element of a given … See more There are (at least) 10 different ways to classify space groups into classes. The relations between some of these are described in the following table. Each classification … See more Note: An e plane is a double glide plane, one having glides in two different directions. They are found in seven orthorhombic, five tetragonal and five cubic space … See more Space groups in 2 dimensions are the 17 wallpaper groups which have been known for several centuries, though the proof that the list was … See more There are at least ten methods of naming space groups. Some of these methods can assign several different names to the same space group, … See more Bieberbach's theorems In n dimensions, an affine space group, or Bieberbach group, is a discrete subgroup of isometries of n-dimensional Euclidean space with a compact fundamental domain. Bieberbach (1911, 1912) proved that the subgroup … See more iot honeypot github
