Order 1728.
786 conjugacy classes of subgroups.
The subgroup lattice has 316 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #11720331 | C2 | semidirect |
| 11. C22×C9×Dic3 | C4 | semidirect |
| 134. C22×Dic3 | Dic9 | semidirect |
| 176. C3×C9 | #381 | semidirect |
| 267. C9 | #4943 | semidirect |
| 308. C3 | #10588891 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
