Order 15616.
520 conjugacy classes of subgroups.
The subgroup lattice has 364 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #21460724 | C2 | semidirect |
| 209. C61 | #8122 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
