Order 1728.
362 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 |
|---|---|---|
| 9. #88532 | C4 | semidirect |
| 14. C9×#208 | C4 | semidirect |
| 132. #208 | Dic9 | semidirect |
| 169. C3×C9 | #343 | semidirect |
| 256. C9 | #4530 | semidirect |
| 294. C3 | #10588234 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
