Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C211⋊C27 | C3 | direct (N × H) |
| 6. C3×C211 | C27 | semidirect |
| 8. C211 | C3×C27 | semidirect |
| 15. C3 | C211⋊C27 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
