Point Groups: Retrieval Tools
10/2014: New shell in related to the two-dimensional and three-dimensional crystallographic point groups. In that new shell one can find programs to access to the generators/general positions and the Wyckoff positions informations.
MAXSUB, CELLSUB, SUBGROUPGRAPH & HERMANN
2-2006: The subgroups suite for space groups now works with tetragonal and hexagonal maximal isomorphic subgroups of indices 5 and 7. Now index factorizations like 14, 20 or 21 are available from the subgroups programs.
NORMALIZER & WYCKSETS
2-2006: Updated version of NORMALIZER & WYCKSETS programs. Added Euclidean/Affine normalizers symbols and table of Wyckoff Sets in main form.
1-2006: Added t-index and k-index information and group-subgroup relation type. Link to COSETS program.
1-2006: New program for the coset decomposition of a group-subgroup pair
11-2005: New program for calculating common subgroups for several space groups
11-2005: New interfaces for obtaining common subgroups of two space groups
10-2005: New options for filtering outbut by point group, crystal system or centering. Also available on CELLSUPER
