Order 16256.
400 conjugacy classes of subgroups.
The subgroup lattice has 146 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #22550007 | C2 | direct (N × H) |
| 23. C2×C127⋊C8 | Q8 | semidirect |
| 42. C127⋊C8 | C2×Q8 | semidirect |
| 68. C2×C127 | #446 | semidirect |
| 73. C127 | C2×#446 | semidirect |
| 141. C2 | #22550007 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
