Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #21443638 | C2 | direct (N × H) |
| 21. C2×C61 | C128 | semidirect |
| 26. C61 | C2×C128 | semidirect |
| 39. C2 | #21443638 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
