Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. C3⋊C16 | C5 | direct (N × H) |
| 10. C3×C5 | C16 | semidirect |
| 15. C5 | C3⋊C16 | direct (N × H) |
| 17. C3 | C5×C16 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
