The concept of crystal structure is intimately related to the notion of symmetry. W.L. Bragg published the description of the first structures only a year after the discovery of diffraction by crystals a century ago. By combining both diffraction and symmetry considerations he could solve the first crystal structures. The description of the symmetry properties of the 230 space groups a few years later by P. Niggli in 1919 is at the origin of the tremendous success of diffraction methods for the elucidation of structures. Space groups are systematically used nowadays to solve, describe and classify any of them.
The paradigm of the three dimensional periodicity of crystalline matter ended up in the 1970’s when aperiodic structures were discovered. The classical concept of three-dimensional symmetry had to be extended to higher dimensional symmetry considerations. Currently, it is not unusual to describe well-ordered structures but aperiodic ones in space up to six dimensions, in the frame of the so-called superspace symmetry groups.
It is the aim of this special issue of Symmetry to present a broad spectrum of modern and recent aspects of symmetry considerations, which are at the disposal of the specialists in order to improve our understanding of the fine structure details of crystalline solids.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed Open Access monthly journal published by MDPI.

Abstract: The use of magnetic symmetry groups (Shubnikov) in the description and analysis of commensurate magnetic structures is becoming increasingly common. The cells, operators and group symbols of Belov, Neronova and Smirnova (BNS) and of Opechowski and Guccione (OG) provide two equivalent but somewhat different systems for describing a Shubnikov group. We will review the use of and the relationship between these two systems in the context of alternative space-group settings.
