Order 1152.
450 conjugacy classes of subgroups.
The subgroup lattice has 312 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 21. #63450 | C4 | semidirect |
| 42. C2×C8×C9 | Q8 | semidirect |
| 58. C2×C9⋊C8 | Q8 | semidirect |
| 219. C2×C8 | Dic18 | semidirect |
| 250. C9 | #1990 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
