Order 1152.
390 conjugacy classes of subgroups.
The subgroup lattice has 225 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. C9×#125 | C4 | semidirect |
| 114. #125 | Dic9 | semidirect |
| 180. C9 | #1989 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
