Order 15616.
1170 conjugacy classes of subgroups.
The subgroup lattice has 322 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #21454908 | C2 | semidirect |
| 2. #21444171 | C2 | semidirect |
| 3. #21444160 | C2 | semidirect |
| 4. #21444140 | C2 | semidirect |
| 183. C61 | #17425 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
