Order 1152.
258 conjugacy classes of subgroups.
The subgroup lattice has 198 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 12. C9×#97 | C4 | semidirect |
| 13. C4×C8×C9 | C4 | semidirect |
| 112. #97 | Dic9 | semidirect |
| 113. C4×C8 | Dic9 | semidirect |
| 162. C9 | #1833 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
