Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C52×C17 | C3 | semidirect |
| 3. C52⋊C3 | C17 | direct (N × H) |
| 5. C52 | C3×C17 | semidirect |
| 6. C17 | C52⋊C3 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
| subgroup | index |
