Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C5×SL(2,𝔽5) | C2 | semidirect |
| 3. #6729 | C5 | direct (N × H) |
| 7. SL(2,𝔽5) | C2×C5 | semidirect |
| 45. C5 | #6729 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
