WebThe 36 cubic crystallographic space groups are different from the remaining 194 space groups in that they each have body diagonal 3-fold axes arising from their tetrahedral and octahedral point groups. These body diagonal 3-fold axes make their orbifolds a less understood topology problem in that the Siefert fibered spaces approach of lifting ...
