Order 1280.
898 conjugacy classes of subgroups.
The subgroup lattice has 272 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 23. #65120 | C4 | semidirect |
| 251. C5 | #20573 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
