Order 1152.
336 conjugacy classes of subgroups.
The subgroup lattice has 294 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 233. C9 | #2086 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
