Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C9×SL(2,𝔽3) | C2 | semidirect |
| 6. Q8×C9 | D3 | semidirect |
| 12. GL(2,𝔽3) | C9 | direct (N × H) |
| 21. SL(2,𝔽3) | C2×C9 | semidirect |
| 34. C9 | GL(2,𝔽3) | direct (N × H) |
| 35. Q8 | D3×C9 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
