Order 1728.
610 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. C3×C4×Dic9 | C4 | semidirect |
| 14. Dic3×Dic9 | C4 | semidirect |
| 57. C4×Dic9 | Dic3 | semidirect |
| 167. C3×C9 | #376 | semidirect |
| 253. C9 | #4932 | semidirect |
| 294. C3 | #10588328 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
