Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C7×C4⋊C4 | C2 | semidirect |
| 3. C42×C7 | C2 | semidirect |
| 7. #126 | C7 | direct (N × H) |
| 12. C4⋊C4 | C2×C7 | semidirect |
| 14. C42 | C2×C7 | semidirect |
| 20. C7 | #126 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
