Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C163⋊#401 | C2 | semidirect |
| 3. #401×C163 | C2 | semidirect |
| 21. D163 | #401 | direct (N × H) |
| 22. C163 | C2×#401 | semidirect |
| 25. #401 | D163 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
