Order 1728.
518 conjugacy classes of subgroups.
The subgroup lattice has 280 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #11720268 | C2 | semidirect |
| 11. C2×C3×Dic18 | C4 | semidirect |
| 57. C2×Dic18 | Dic3 | semidirect |
| 168. C3×C9 | #419 | semidirect |
| 243. C9 | #5225 | semidirect |
| 274. C3 | #10588681 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
