Order 1728.
554 conjugacy classes of subgroups.
The subgroup lattice has 274 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. #10588657 | C3 | direct (N × H) |
| 13. C3×C4×Dic9 | C4 | semidirect |
| 52. C4×Dic9 | C3×C4 | semidirect |
| 151. C3×C9 | #382 | semidirect |
| 229. C9 | C3×#382 | semidirect |
| 266. C3 | #10588657 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
