Order 15616.
644 conjugacy classes of subgroups.
The subgroup lattice has 420 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. C2×#16840622 | C2 | semidirect |
| 4. #21460697 | C2 | semidirect |
| 187. C2×D61 | #333 | semidirect |
| 234. C61 | #9127 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
