Order 1080.
78 conjugacy classes of subgroups.
| subgroup | G/H | |
|---|---|---|
| center, Fitting, hypercenter | C2×C9 | A5 |
| commutator, hypocenter | A5 | C2×C9 |
| Frattini, cosocle | C3 | C2×C3×A5 |
| socle, prime radical | C2×C3×A5 | C3 |
| LCS | G ▷ A5 | |
| UCS | C1 ◁ C2×C9 | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C9×A5 | C2 | direct (N × H) |
| 6. C2×A5 | C9 | direct (N × H) |
| 16. A5 | C2×C9 | direct (N × H) |
| 41. C2×C9 | A5 | direct (N × H) |
| 54. C9 | C2×A5 | direct (N × H) |
| 72. C2 | C9×A5 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
