Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C7×C25 | C5 | semidirect |
| 3. 5−1+2 | C7 | direct (N × H) |
| 7. C25 | C5×C7 | semidirect |
| 8. C7 | 5−1+2 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
