Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #157 | C4 | direct (N × H) |
| 5. C32×C4 | C4 | semidirect |
| 6. C3⋊Dic3 | C4 | semidirect |
| 14. C32 | C42 | semidirect |
| 22. C4 | #157 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
