Order 15616.
1062 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. #21445961 | C2 | semidirect |
| 76. C4×Dic61 | M16 | semidirect |
| 147. C61 | #20772 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
