Order 15616.
888 conjugacy classes of subgroups.
The subgroup lattice has 420 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #21456967 | C2 | semidirect |
| 3. #21444861 | C2 | semidirect |
| 5. #21444383 | C2 | semidirect |
| 244. C61 | #18311 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
