Order 720.
54 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. Dic36 | C5 | direct (N × H) |
| 16. C5×C9 | Q16 | semidirect |
| 32. C9 | C5×Q16 | semidirect |
| 36. C5 | Dic36 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
| subgroup | index |
|---|---|
| C5×Dic18 | 2 |
| C5×C8×C9 | 2 |
| C5×Dic12 | 3 |
