Order 1728.
446 conjugacy classes of subgroups.
The subgroup lattice has 256 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. Dic9⋊(C3⋊C8) | C2 | semidirect |
| 65. C3×Dic9 | M16 | semidirect |
| 147. Dic9 | #208 | semidirect |
| 152. C3×C9 | #423 | semidirect |
| 221. C9 | #4924 | semidirect |
| 250. C3 | #10588802 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
