Order 1152.
360 conjugacy classes of subgroups.
The subgroup lattice has 216 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 13. C9×#106 | C4 | semidirect |
| 68. C8×C9 | C4⋊C4 | semidirect |
| 113. #106 | Dic9 | semidirect |
| 171. C9 | #1944 | semidirect |
| 190. C8 | C4⋊Dic9 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
