Order 15616.
1214 conjugacy classes of subgroups.
The subgroup lattice has 454 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #21461083 | C2 | semidirect |
| 3. #21461082 | C2 | semidirect |
| 5. #21461061 | C2 | semidirect |
| 125. C2×Dic122 | M16 | semidirect |
| 257. C61 | #17365 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
