Order 720.
60 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. Dic90 | C2 | semidirect |
| 3. C9⋊#168 | C2 | semidirect |
| 22. C5×C9 | SD16 | semidirect |
| 46. C9 | #687 | semidirect |
| 52. C5 | #3672 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
