Order 22784.
950 conjugacy classes of subgroups.
The subgroup lattice has 252 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #26020381 | C2 | semidirect |
| 4. #26020378 | C2 | semidirect |
| 11. C2×C8×Dic89 | C4 | semidirect |
| 133. C89 | #20760 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
