Order 1728.
486 conjugacy classes of subgroups.
The subgroup lattice has 268 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #11720273 | C2 | semidirect |
| 67. C3⋊Dic9 | M16 | semidirect |
| 160. C3×C9 | #423 | semidirect |
| 233. C9 | #5118 | semidirect |
| 262. C3 | #10588802 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
