Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C127×C131 | C2 | semidirect |
| 2. D131 | C127 | direct (N × H) |
| 4. C131 | C2×C127 | semidirect |
| 5. C127 | D131 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
