Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. C2×#125 | C2 | direct (N × H) |
| 8. #125 | C22 | direct (N × H) |
| 31. C22 | #125 | direct (N × H) |
| 38. C2 | C2×#125 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
