Order 1280.
598 conjugacy classes of subgroups.
The subgroup lattice has 268 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #10598199 | C2 | semidirect |
| 240. C5 | #7988 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
