Space Groups Projections
The program PROJECTIONS identifies the plane group symmetry of a projection of a space group along a projection direction. 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:


    Assumed lattice translations:
    x + 1 , y , z
    x , y + 1 , z
    x , y , z + 1
