Order 1280.
870 conjugacy classes of subgroups.
The subgroup lattice has 278 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. #10599721 | C2 | direct (N × H) |
| 225. C2×C5 | #1837 | semidirect |
| 256. C5 | C2×#1837 | semidirect |
| 274. C2 | #10599721 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
