Order 1728.
670 conjugacy classes of subgroups.
The subgroup lattice has 338 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 54. C3×Dic18 | Q8 | semidirect |
| 147. Dic18 | Dic6 | semidirect |
| 221. C3×C9 | #557 | semidirect |
| 301. C9 | #5570 | semidirect |
| 332. C3 | #10589823 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
