Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #15688500 | C9 | direct (N × H) |
| 13. C9×C37 | C81 | semidirect |
| 24. C37 | C9×C81 | semidirect |
| 30. C9 | #15688500 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
