Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C5×C25 | C2 | semidirect |
| 6. C25 | D5 | direct (N × H) |
| 8. D5 | C25 | direct (N × H) |
| 10. C5 | C2×C25 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
