Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. AGL(1,𝔽8) | C2 | direct (N × H) |
| 2. C24 | C7 | semidirect |
| 6. C23 | C2×C7 | semidirect |
| 13. C2 | AGL(1,𝔽8) | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
