Superspace Finder v2.0 Beta version
3D derivatives of (3+1)D space groups in analytical form
  • Displays commensurate cuts of superspace groups
  • Finds common (3+1)D denominator for a set of 3D groups
  • Of special use for phase transitions and modular structures
Browse (3+1)D groups...

First, select the crystal system, then browse the categories from left to right.

3+1D to 3D group transformation for commensurate modulation

N1, N2, N3 - denominators of q-vector components (simple N if there is only one component).
3D derivatives inherit basis of parental (3+1)D group.
To obtain specific group orientation and symbol a basis transofrmation might be necessary.


Constraints of t level. Variable n stands for any integer.

...or search for 3D group set

Type desired 3D space groups separated by space.
