Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. C163⋊C32 | C4 | direct (N × H) |
| 18. C4×C163 | C32 | semidirect |
| 23. C163 | C4×C32 | semidirect |
| 42. C4 | C163⋊C32 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
