Order 320.
82 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. Dic40 | C2 | direct (N × H) |
| 28. C2×C5 | Q32 | semidirect |
| 36. C5 | C2×Q32 | semidirect |
| 41. C2 | Dic40 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
| subgroup | index |
|---|---|
| C2×Dic20 | 2 |
| C2×C5×C16 | 2 |
