Order 22784.
1290 conjugacy classes of subgroups.
The subgroup lattice has 262 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 15. #395×C89 | C4 | semidirect |
| 22. C2×C4⋊Dic89 | Q8 | semidirect |
| 136. C89 | #14601 | semidirect |
| 142. #395 | Dic89 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
