Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C2×C52⋊C3 | C2 | semidirect |
| 2. #3874 | C2 | direct (N × H) |
| 4. C52⋊C3 | C22 | semidirect |
| 5. C2×C52 | D3 | semidirect |
| 7. C52 | C2×D3 | semidirect |
| 22. C2 | #3874 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
