Order 22784.
1182 conjugacy classes of subgroups.
The subgroup lattice has 290 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #26020378 | C2 | direct (N × H) |
| 12. C2×C8×Dic89 | C4 | semidirect |
| 39. C8×Dic89 | C2×C4 | semidirect |
| 139. C2×C89 | #1834 | semidirect |
| 151. C89 | C2×#1834 | semidirect |
| 283. C2 | #26020378 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
