Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. C4×C52 | C3 | semidirect |
| 3. C52⋊C3 | C4 | direct (N × H) |
| 5. C52 | C3×C4 | semidirect |
| 11. C4 | C52⋊C3 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
