Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C3⋊PSU(3,𝔽2) | C2 | semidirect |
| 3. C3×AGL(1,𝔽9) | C2 | semidirect |
| 10. AGL(1,𝔽9) | D3 | semidirect |
| 18. C33 | SD16 | semidirect |
| 35. C32 | #204 | semidirect |
| 50. C3 | AΓL(1,𝔽9) | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
