Common Subgroups of Space Groups
Common Subgroups
COMMONSUBS
calculates the common subgroups of space groups given:
The space group ITA numbers.
The numbers of formula units (per conventional unit cell).
A maximum k-index which defines the maximum cell multiplication in the subgroup.
Only the
default choice
for the conventional setting of the space groups is used.
Enter the sequential numbers of the space groups (separated by commas)
Enter the corresponding numbers of formula units (conventional)
