Order 15616.
906 conjugacy classes of subgroups.
The subgroup lattice has 508 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #21460690 | C2 | semidirect |
| 257. D61 | #1293 | semidirect |
| 281. C61 | C2×#1293 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
