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×#107 | C4 | semidirect |
| 13. C9×#106 | C4 | semidirect |
| 14. C8×Dic9 | C4 | semidirect |
| 15. #63372 | C4 | semidirect |
| 107. #107 | Dic9 | semidirect |
| 108. #106 | Dic9 | semidirect |
| 159. C9 | #1772 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
