Order 22784.
822 conjugacy classes of subgroups.
The subgroup lattice has 282 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 |
| 116. Dic178 | #107 | semidirect |
| 149. C89 | #22740 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
