Order 1728.
470 conjugacy classes of subgroups.
The subgroup lattice has 264 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 46. C3⋊(C9⋊C8) | Q8 | semidirect |
| 169. C3×C9 | #446 | semidirect |
| 230. C9 | #4828 | semidirect |
| 258. C3 | #10588510 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
