Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #6891 | C2 | semidirect |
| 4. #4181 | C3 | semidirect |
| 6. C3×3−1+2 | D3 | semidirect |
| 9. C32⋊C9 | C2×C3 | semidirect |
| 24. C3×C9 | C3×D3 | semidirect |
| 42. C32 | AGL(1,ℤ/9) | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
