Order 22784.
2430 conjugacy classes of subgroups.
The subgroup lattice has 378 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #26018480 | C2 | semidirect |
| 5. #26018477 | C2 | semidirect |
| 13. C22×C4×Dic89 | C4 | semidirect |

| 179. Dic89 | #381 | semidirect |
| 196. C89 | #14685 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
