Order 16448.
186 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. D257⋊M16 | C2 | semidirect |
| 2. #22551652 | C2 | semidirect |
| 5. #16861627 | C22 | semidirect |
| 45. D257 | #100 | semidirect |
| 46. C257 | C2×#100 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
