Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 14. C4×C509 | Q8 | semidirect |
| 17. Dic509 | Q8 | semidirect |
| 21. C509 | C4⋊Q8 | semidirect |
| 39. C4 | Dic1018 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
