Order 1728.
338 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 |
|---|---|---|
| 9. C2×C3⋊(C9⋊C8) | C4 | semidirect |
| 14. C3×#3667 | C4 | semidirect |
| 55. #3667 | Dic3 | semidirect |
| 161. C3×C9 | #344 | semidirect |
| 240. C9 | #4559 | semidirect |
| 273. C3 | #10588209 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
