Order 22784.
1942 conjugacy classes of subgroups.
The subgroup lattice has 320 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 21. #395×C89 | C4 | semidirect |
| 38. C2×C4×Dic89 | Q8 | semidirect |
| 116. C2×C4×C89 | C4×Q8 | semidirect |
| 151. Dic89 | #395 | direct (N × H) |
| 167. C89 | C4×#395 | semidirect |
| 176. #395 | Dic89 | direct (N × H) |
| 292. C2×C4 | Q8×Dic89 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
