All of this information can be found elsewhere on the site, but here is a quick reference sheet if you want to study the basic crystals quickly before an exam. Here are the links for the thorough...

Here is a list of the 230 3-dimensional space groups, organized by crystal system. Each space group is labeled according to its number, abbreviated Hermann–Mauguin notation (international...

This is another of those articles that clarifies subtle terminology differences, plus a bonus chart that discusses the relationship between Bravais lattices, point groups, and space groups...

So, you want to know what a crystal system is. If that’s the case, you might not be 100% clear on the difference between crystal system, crystal structure, crystal family, crystal lattices, or...

This article lists all the 3D and 2D point groups, including alternate notations, related space groups, and allowed/forbidden properties in tabular format. If you want help understanding concepts,...
