Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C5×A6 | C2 | semidirect |
| 2. PGL(2,𝔽9) | C5 | direct (N × H) |
| 4. A6 | C2×C5 | semidirect |
| 46. C5 | PGL(2,𝔽9) | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
