Order 576.
162 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. C9×Q16 | C4 | semidirect |
| 59. Q16 | Dic9 | semidirect |
| 72. C9 | #441 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
