Order 32128.
416 conjugacy classes of subgroups.
The subgroup lattice has 166 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #30631441 | C2 | semidirect |
| 7. C22×C251⋊C8 | C4 | semidirect |
| 17. C2×M16×C251 | C4 | semidirect |
| 82. C251 | #1729 | semidirect |
| 91. C2×M16 | Dic251 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
