Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C43⋊C128 | C2 | semidirect |
| 3. C43×C128 | C2 | semidirect |
| 22. C128 | D43 | semidirect |
| 28. C43 | M256 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
