Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. Q8⋊C9 | C3 | direct (N × H) |
| 6. C3×Q8 | C9 | semidirect |
| 14. Q8 | C3×C9 | semidirect |
| 18. C3 | Q8⋊C9 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
