Order 1280.
1510 conjugacy classes of subgroups.
The subgroup lattice has 400 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. C2×#4072 | C4 | semidirect |
| 15. C5×#381 | C4 | semidirect |
| 20. C2×#3963 | C4 | semidirect |
| 127. #381 | Dic5 | semidirect |
| 357. C5 | #10736 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
