Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C3×Q8 | C3 | direct (N × H) |
| 5. C32 | Q8 | direct (N × H) |
| 6. Q8 | C32 | direct (N × H) |
| 9. C3 | C3×Q8 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
