Order 1728.
538 conjugacy classes of subgroups.
The subgroup lattice has 302 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 13. C4×C9×Dic3 | C4 | semidirect |
| 134. C4×Dic3 | Dic9 | semidirect |
| 167. C3×C9 | #382 | semidirect |
| 253. C9 | #4650 | semidirect |
| 294. C3 | #10588616 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
