Order 32128.
612 conjugacy classes of subgroups.
The subgroup lattice has 250 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 11. C2×Dic251⋊C4 | C4 | semidirect |
| 14. C251⋊#95 | C4 | semidirect |
| 67. C2×Dic251 | C42 | semidirect |
| 88. C2×C4×C251 | C4⋊C4 | semidirect |
| 124. C251 | #1436 | semidirect |
| 213. C2×C4 | Dic251⋊C4 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
