Order 576.
111 conjugacy classes of subgroups.
| subgroup | G/H | |
|---|---|---|
| center, hypercenter | C4×C8 | D9 |
| commutator, hypocenter | C9 | C82 |
| Frattini | C3×C42 | C2×D3 |
| Fitting | C4×C8×C9 | C2 |
| socle, prime radical | C22×C3 | C4×Dic3 |
| cosocle | C42×C9 | C22 |
| LCS | G ▷ C9 | |
| UCS | C1 ◁ C4×C8 | |
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. C8×C9 | C8 | semidirect |
| 12. C9⋊C8 | C8 | direct (N × H) |
| 34. C9 | C82 | semidirect |
| 38. C8 | C9⋊C8 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
| subgroup | index |
