Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C3×C49 | C2 | semidirect |
| 2. D49 | C3 | direct (N × H) |
| 3. C49 | C2×C3 | semidirect |
| 9. C3 | D49 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
