Order 1280.
538 conjugacy classes of subgroups.
The subgroup lattice has 266 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. C2×#64731 | C2 | semidirect |
| 5. #10598301 | C2 | semidirect |
| 163. C22×C5 | #364 | semidirect |
| 243. C5 | #12788 | semidirect |
| 249. C22 | #64731 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
