Order 15616.
1100 conjugacy classes of subgroups.
The subgroup lattice has 600 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #21462011 | C2 | semidirect |
| 4. #21461962 | C2 | semidirect |
| 6. #21461572 | C2 | semidirect |
| 250. C2×Dic61 | #101 | semidirect |
| 342. C61 | #21425 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
