Order 1728.
750 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 |
|---|---|---|
| 153. C3×C9 | #398 | semidirect |
| 221. C9 | #4981 | semidirect |
| 256. C3 | #10588661 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
