Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C32×C607 | C3 | semidirect |
| 4. C607 | H(3,𝔽3) | direct (N × H) |
| 5. H(3,𝔽3) | C607 | direct (N × H) |
| 6. C32 | C3×C607 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
