Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. Dic3 | C2 | direct (N × H) |
| 4. C2×C3 | C4 | semidirect |
| 8. C3 | C2×C4 | semidirect |
| 9. C2 | Dic3 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
