Order 720.
60 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C9×#168 | C2 | semidirect |
| 12. #681 | C9 | direct (N × H) |
| 19. C5×C9 | M16 | semidirect |
| 21. #168 | C2×C9 | semidirect |
| 41. C9 | #681 | direct (N × H) |
| 46. C5 | C9×M16 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
