Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C5×C23 | C3 | direct (N × H) |
| 2. C3×C23 | C5 | direct (N × H) |
| 3. C23 | C3×C5 | direct (N × H) |
| 4. C3×C5 | C23 | direct (N × H) |
| 5. C5 | C3×C23 | direct (N × H) |
| 6. C3 | C5×C23 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
