Order 32128.
736 conjugacy classes of subgroups.
The subgroup lattice has 312 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. C2×C251⋊#95 | C2 | semidirect |
| 4. C2×C251⋊#95 | C2 | semidirect |
| 13. C2×C22⋊Dic251 | C4 | semidirect |
| 155. C251 | #1440 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
