Order 1152.
546 conjugacy classes of subgroups.
The subgroup lattice has 204 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. #10588359 | C2 | semidirect |
| 7. C8×Dic18 | C2 | semidirect |
| 35. C2×C8×C9 | Q8 | semidirect |
| 151. C2×C8 | Dic18 | semidirect |
| 172. C9 | #2960 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
