are given with spaces for readability. The groups each have a point group of the unit cell. In Hermann–Mauguin notation, space groups are named by a symbol...

Leonhard Sohncke listed the 65 space groups (called Sohncke groups) whose elements preserve the chirality. More accurately, he listed 66 groups, but both the...

point groups are not enough to describe the full symmetry of crystals, so the full space group is usually used instead. The naming of full space groups usually...

simple Lie group is a connected non-abelian Lie group G which does not have nontrivial connected normal subgroups. The list of simple Lie groups can be used...

This list of space telescopes (astronomical space observatories) is grouped by major frequency ranges: gamma ray, x-ray, ultraviolet, visible, infrared...

This is a list of color spaces, grouped by the color model that is used for part of their specification. Color models can be based on physics or human...

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...
