Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C37×C121 | C7 | direct (N × H) |
| 3. C7×C121 | C37 | direct (N × H) |
| 5. C7×C37 | C121 | direct (N × H) |
| 6. C121 | C7×C37 | direct (N × H) |
| 8. C37 | C7×C121 | direct (N × H) |
| 10. C7 | C37×C121 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
