Order 1152.
360 conjugacy classes of subgroups.
The subgroup lattice has 240 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. C9×C4⋊Q8 | C4 | semidirect |
| 7. C9×C4⋊Q8 | C4 | semidirect |
| 12. C4×Q8×C9 | C4 | semidirect |
| 120. C4⋊Q8 | Dic9 | semidirect |
| 121. C4⋊Q8 | Dic9 | semidirect |
| 126. C4×Q8 | Dic9 | semidirect |
| 194. C9 | #1503 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
