Order 1152.
540 conjugacy classes of subgroups.
The subgroup lattice has 204 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. #10588558 | C2 | direct (N × H) |
| 135. C2×C9 | #499 | semidirect |
| 167. C9 | C2×#499 | semidirect |
| 199. C2 | #10588558 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
