Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C2×C121 | C2 | semidirect |
| 2. D121 | C2 | direct (N × H) |
| 3. C121 | C22 | semidirect |
| 10. C2 | D121 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
