Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C112 | C2 | semidirect |
| 3. D11 | C11 | direct (N × H) |
| 5. C11 | D11 | direct (N × H) |
| 6. C11 | C2×C11 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
