Order 16448.
96 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #22551584 | C2 | semidirect |
| 3. #22551517 | C2 | semidirect |
| 5. C4×C8×C257 | C2 | semidirect |
| 31. C257 | #488 | semidirect |
| 37. C4×C8 | D257 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
