Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. SL(2,𝔽3) | C2 | direct (N × H) |
| 2. C2×Q8 | C3 | semidirect |
| 5. Q8 | C2×C3 | semidirect |
| 13. C2 | SL(2,𝔽3) | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
