Order 22784.
1214 conjugacy classes of subgroups.
The subgroup lattice has 534 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #26018595 | C2 | semidirect |
| 5. #26018575 | C2 | semidirect |
| 121. C2×Dic178 | M16 | semidirect |
| 273. C89 | #17365 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
