Order 1728.
1000 conjugacy classes of subgroups.
The subgroup lattice has 294 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 53. #6226 | Q8 | semidirect |
| 197. C3×C9 | #557 | semidirect |
| 261. C9 | #5721 | semidirect |
| 288. C3 | #10589823 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
