Order 22784.
1862 conjugacy classes of subgroups.
The subgroup lattice has 342 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #26018511 | C2 | semidirect |
| 4. #26018478 | C2 | semidirect |
| 10. C4×C22⋊Dic89 | C4 | semidirect |
| 32. C2×C4×Dic89 | C2×C4 | semidirect |
| 37. #15667919 | C2×C4 | semidirect |
| 177. C89 | #13966 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
