WebMar 26, 2024 · Two crystallographic groups are said to be equivalent if they are conjugate in the group of affine transformations of $ E ^ {n} $. The origin of the theory of … WebThe same distinction between groups and types of groups must also be made for point groups. The common statement that there are 32 crystallographic point groups (in three-dimensional space) is again, strictly speaking, incorrect because it actually applies to point-group types. As already seen in the case of space groups, point groups too are ...
