Order 320.
100 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. C2×Dic20 | C2 | semidirect |
| 4. #3956 | C2 | semidirect |
| 5. #3951 | C2 | semidirect |
| 67. C5 | #473 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
