Order 400.
68 conjugacy classes of subgroups.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 7. C5×Dic5 | C4 | semidirect |
| 9. #683 | C5 | direct (N × H) |
| 20. C52 | C4⋊C4 | semidirect |
| 30. Dic5 | C4×C5 | semidirect |
| 45. C5 | #683 | direct (N × H) |
| 46. C5 | C5×C4⋊C4 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
