Order 15616.
1956 conjugacy classes of subgroups.
The subgroup lattice has 284 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. D61⋊#338 | C2 | semidirect |
| 3. C2×#16840631 | C2 | semidirect |
| 161. C61 | #20340 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
