Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 6. C5×#401 | C4 | semidirect |
| 8. C5⋊#401 | C4 | semidirect |
| 32. #401 | AGL(1,𝔽5) | direct (N × H) |
| 57. AGL(1,𝔽5) | #401 | direct (N × H) |
| 84. C5 | C4×#401 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
