Order 1152.
522 conjugacy classes of subgroups.
The subgroup lattice has 192 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. #10588381 | C2 | semidirect |
| 32. C2×C8×C9 | Q8 | semidirect |
| 141. C2×C8 | Dic18 | semidirect |
| 161. C9 | #2961 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
