Order 576.
165 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C9×#125 | C2 | semidirect |
| 3. #63369 | C2 | semidirect |
| 4. #63362 | C2 | semidirect |
| 37. #125 | D9 | semidirect |
| 62. C9 | #490 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
