Order 15616.
1246 conjugacy classes of subgroups.
The subgroup lattice has 556 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #21461329 | C2 | semidirect |
| 4. #21461328 | C2 | semidirect |
| 5. D61⋊#332 | C2 | semidirect |
| 21. #16840621 | C22 | semidirect |
| 283. D61 | #1546 | semidirect |
| 316. C61 | C2×#1546 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
