Order 15616.
1162 conjugacy classes of subgroups.
The subgroup lattice has 350 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 1. #21462714 | C2 | semidirect |
| 2. #21461062 | C2 | semidirect |
| 3. #21461061 | C2 | semidirect |
| 34. C2×Q8×D61 | C8 | semidirect |
| 199. C61 | #17352 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
