Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C9×A5 | C2 | semidirect |
| 6. S5 | C9 | direct (N × H) |
| 13. A5 | C2×C9 | semidirect |
| 45. C9 | S5 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
