Order 22784.
578 conjugacy classes of subgroups.
The subgroup lattice has 388 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #26018077 | C2 | semidirect |
| 4. #26018074 | C2 | semidirect |
| 29. #15667991 | C8 | semidirect |
| 60. C2×Dic178 | C2×C8 | semidirect |
| 72. C4⋊Dic89 | C2×C8 | semidirect |
| 199. C89 | #7589 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
