Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C92 | C3 | direct (N × H) |
| 4. C3×C9 | C9 | direct (N × H) |
| 8. C9 | C3×C9 | direct (N × H) |
| 9. C3 | C92 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
