Order 1728.
494 conjugacy classes of subgroups.
The subgroup lattice has 296 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 165. C3×C9 | #400 | semidirect |
| 248. C9 | #4659 | semidirect |
| 288. C3 | #10588666 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
