Order 400.
56 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C5×Dic10 | C2 | semidirect |
| 3. C5×#168 | C2 | semidirect |
| 8. #687 | C5 | direct (N × H) |
| 15. Dic10 | C2×C5 | semidirect |
| 17. #168 | C2×C5 | semidirect |
| 18. C52 | SD16 | semidirect |
| 38. C5 | #687 | direct (N × H) |
| 39. C5 | C5×SD16 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
