Order 1728.
344 conjugacy classes of subgroups.
The subgroup lattice has 236 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 32. C9×Dic6 | C8 | semidirect |
| 35. C9×C3⋊C8 | Q8 | semidirect |
| 37. #4830 | C9 | direct (N × H) |
| 142. C3×C9 | C8×Q8 | semidirect |
| 157. Dic6 | C8×C9 | semidirect |
| 164. C3⋊C8 | Q8×C9 | semidirect |
| 203. C9 | #4830 | direct (N × H) |
| 230. C3 | C8×Q8×C9 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
