Crystallographic table
WebThe space-group numbers were introduced in International Tables for X-ray Crystallography (1952) [referred to as IT (1952 )] for plane groups (Nos. 1–17) and space groups (Nos. 1–230). They provide a short way of specifying the type of a space group uniquely, albeit without reference to its symmetries. WebThe IUCr is an International Scientific Union.
