Order 1728.
594 conjugacy classes of subgroups.
The subgroup lattice has 274 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. C9×#836 | C2 | direct (N × H) |
| 34. C2×#836 | C9 | direct (N × H) |
| 72. #836 | C2×C9 | direct (N × H) |
| 108. C2×C3×C9 | #101 | semidirect |
| 158. C3×C9 | C2×#101 | semidirect |
| 201. C2×C9 | #836 | direct (N × H) |
| 235. C9 | C2×#836 | direct (N × H) |
| 255. C2×C3 | C9×#101 | semidirect |
| 267. C3 | C2×C9×#101 | semidirect |
| 271. C2 | C9×#836 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
