Order 1280.
494 conjugacy classes of subgroups.
The subgroup lattice has 216 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. C5×#500 | C4 | semidirect |
| 75. #500 | Dic5 | semidirect |
| 196. C5 | #9831 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
