Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C877⋊C9 | C2 | direct (N × H) |
| 4. C2×C877 | C9 | semidirect |
| 5. C877 | C2×C9 | semidirect |
| 10. C2 | C877⋊C9 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
