Order 22784.
978 conjugacy classes of subgroups.
The subgroup lattice has 346 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #26020970 | C2 | semidirect |
| 4. #26020968 | C2 | semidirect |
| 30. C2×C4⋊Dic89 | C8 | semidirect |
| 117. C2×C4×C89 | C4⋊C8 | semidirect |
| 179. C89 | #21951 | semidirect |
| 298. C2×C4 | #15667941 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
