Identify layer group symmetry
|
|
The program SECTIONS identifies, for a given space group, the full set of possible layer symmetries of periodic sections defined by their common normal vector and located within the unit cell. The program accepts as input a space group given in any arbitrary setting. The results are expressed in both the given basis of the input space group and the standard setting of the sectional groups.

|
- OPTION A: Space group number
|
Please, enter the sequential number of group as given in the
International Tables for Crystallography, Vol. A or |
|
- OPTION B: Symmetry operations
|
Enter the generators of the Space Group in the box below, given in any basis of the lattice, as in the example:
x+1/2,y+1/2,z
-y+1/3,x+1/4,z+1/4
Assumed lattice translations:
x + 1 , y , z
x , y + 1 , z
x , y , z + 1
