Order 1152.
204 conjugacy classes of subgroups.
The subgroup lattice has 174 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 9. C9×#108 | C4 | semidirect |
| 13. #63371 | C4 | semidirect |
| 91. #108 | Dic9 | semidirect |
| 137. C9 | #1387 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
