Order 22784.
866 conjugacy classes of subgroups.
The subgroup lattice has 386 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #26020810 | C2 | semidirect |
| 3. #26020808 | C2 | semidirect |
| 35. C2×C4⋊Dic89 | C8 | semidirect |
| 200. C89 | #21912 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
