Order 1728.
404 conjugacy classes of subgroups.
The subgroup lattice has 290 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. Dic9⋊(C3⋊C8) | C2 | semidirect |
| 5. C3⋊C8×Dic9 | C2 | semidirect |
| 33. C2×C3×Dic9 | C8 | semidirect |
| 104. C2×Dic9 | C3⋊C8 | semidirect |
| 168. C3×C9 | #431 | semidirect |
| 247. C9 | #4925 | semidirect |
| 283. C3 | #10588398 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
