Order 15616.
1182 conjugacy classes of subgroups.
The subgroup lattice has 422 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #21461921 | C2 | semidirect |
| 5. #21461920 | C2 | semidirect |
| 6. #21461919 | C2 | semidirect |
| 218. D61 | #1940 | semidirect |
| 244. C61 | C2×#1940 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
