Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. A4 | C2 | direct (N × H) |
| 2. C23 | C3 | semidirect |
| 6. C22 | C2×C3 | semidirect |
| 10. C2 | A4 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
