Order 1280.
454 conjugacy classes of subgroups.
The subgroup lattice has 270 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 17. C8×Dic10 | C4 | semidirect |
| 127. Dic10 | #106 | semidirect |
| 130. C5×C8 | #103 | semidirect |
| 245. C8 | #3948 | semidirect |
| 246. C5 | #8643 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
