Order 22784.
990 conjugacy classes of subgroups.
The subgroup lattice has 272 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. C8×Dic178 | C4 | semidirect |
| 31. C4×Dic178 | C8 | semidirect |
| 112. Dic178 | C4×C8 | semidirect |
| 144. C89 | #20569 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
