Order 1152.
348 conjugacy classes of subgroups.
The subgroup lattice has 195 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 12. C9×#108 | C4 | semidirect |
| 13. #63378 | C4 | semidirect |
| 14. #63377 | C4 | semidirect |
| 17. C8×Dic9 | C4 | semidirect |
| 106. #108 | Dic9 | semidirect |
| 159. C9 | #1772 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
