Order 15616.
914 conjugacy classes of subgroups.
The subgroup lattice has 258 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #21446813 | C2 | semidirect |
| 3. #21446809 | C2 | semidirect |
| 151. C61 | #21832 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
