Order 864.
112 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 17. #819 | C9 | direct (N × H) |
| 43. C3×C9 | #108 | semidirect |
| 71. C9 | #819 | direct (N × H) |
| 85. C3 | C9×#108 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
