Order 1728.
542 conjugacy classes of subgroups.
The subgroup lattice has 318 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 7. #10588661 | C3 | direct (N × H) |
| 179. C3×C9 | #398 | semidirect |
| 269. C9 | C3×#398 | semidirect |
| 310. C3 | #10588661 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
