Minimal Supergroups
The list with the minimal supergroup types is given in the table. Each supergroup type is specified by its ITA number and the corresponding Hermann-Mauguin symbol. Also, the index of the supergroup and the supergroup type is given. To see all the transformation matrices that relate the supergroup of a given type with the subgroup, click on the link in the column Subgroup data.

To see all possible supergroups of a given type select the type of the supergroup, and then click over [Show]

To calculate the minimal isomorphic supergroups of index greater than seven click on the link of the index.
