Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C22×C2647 | C3 | semidirect |
| 4. C2647 | A4 | direct (N × H) |
| 5. A4 | C2647 | direct (N × H) |
| 6. C22 | C3×C2647 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
