Order 22784.
522 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 |
|---|---|---|
| 6. C22×Dic356 | C4 | semidirect |
| 12. C2×#15667946 | C4 | semidirect |
| 13. C2×#15667937 | C4 | semidirect |
| 77. C22⋊Dic89 | Q16 | semidirect |
| 176. C89 | #9782 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
