Order 26176.
110 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 5. C4⋊Dic409 | C4 | semidirect |
| 9. C4×Dic409 | C4 | semidirect |
| 12. M16×C409 | C4 | semidirect |
| 39. C409 | #339 | semidirect |
| 47. M16 | Dic409 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
