Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C9⋊SL(2,𝔽3) | C2 | semidirect |
| 3. Q8×D9 | C3 | semidirect |
| 6. Q8×C9 | C2×C3 | semidirect |
| 27. D9 | SL(2,𝔽3) | semidirect |
| 35. C9 | C2×SL(2,𝔽3) | semidirect |
| 37. Q8 | AGL(1,ℤ/9) | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
