Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C31×C289 | C3 | semidirect |
| 5. C289 | C31⋊C3 | direct (N × H) |
| 6. C31⋊C3 | C289 | direct (N × H) |
| 8. C31 | C3×C289 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
