Order 1152.
864 conjugacy classes of subgroups.
The subgroup lattice has 234 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #10588802 | C2 | direct (N × H) |
| 5. C2×Dic9⋊C8 | C2 | semidirect |
| 20. Dic9⋊C8 | C22 | semidirect |
| 77. C2×Dic9 | M16 | semidirect |
| 119. Dic9 | C2×M16 | semidirect |
| 155. C2×C9 | #423 | semidirect |
| 191. C9 | C2×#423 | semidirect |
| 230. C2 | #10588802 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
