Order 400.
48 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 8. #689 | C5 | direct (N × H) |
| 17. C52 | Q16 | semidirect |
| 34. C5 | #689 | direct (N × H) |
| 35. C5 | C5×Q16 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
| subgroup | index |

| C52×Q8 | 2 |
| C5×Dic10 | 2 |
| C5×#168 | 2 |
