Order 720.
54 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 21. C5×C9 | Q16 | semidirect |
| 42. C9 | #689 | semidirect |
| 47. C5 | #3674 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
