Description: Table of generators of the (3+1)-dimensional superspace groups. Table of incommensurate IRs of the (3+1)-dimensional superspace extensions of the 230 crystallographic space groups. Table of incommensurate isotropy subgroups of the (3+1)-dimensional superspace extensions of the 230 crystallographic space groups.

Superceded: These tables have been removed from the suite because they have been superceded by more complete resources that support 1, 2, and 3 incommensurate modulations. An algorithm improvement in 2020 also uncovered additional isotropy subgroups that were not included in the 2007 manuscript.
