Order 324.
70 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. C9×Dic3 | C3 | semidirect |
| 5. C3×3−1+2 | C4 | semidirect |
| 18. 3−1+2 | Dic3 | direct (N × H) |
| 19. C3×C9 | C3×C4 | semidirect |
| 29. Dic3 | 3−1+2 | direct (N × H) |
| 36. C9 | C3×Dic3 | semidirect |
| 46. C3 | C4×3−1+2 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
