Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. Dic10 | C4 | direct (N × H) |
| 16. C4×C5 | Q8 | semidirect |
| 33. C5 | C4×Q8 | semidirect |
| 38. C4 | Dic10 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
