Order 720.
60 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C5×Dic18 | C2 | semidirect |
| 3. C5×C9⋊C8 | C2 | semidirect |
| 8. #3672 | C5 | direct (N × H) |
| 16. Dic18 | C2×C5 | semidirect |
| 17. C9⋊C8 | C2×C5 | semidirect |
| 22. C5×C9 | SD16 | semidirect |
| 46. C9 | C5×SD16 | semidirect |
| 52. C5 | #3672 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
