Order 720.
60 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C9⋊#170 | C2 | semidirect |
| 3. C9×#170 | C2 | semidirect |
| 22. C5×C9 | M16 | semidirect |
| 25. #170 | D9 | semidirect |
| 46. C9 | #704 | semidirect |
| 52. C5 | #3663 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
