Order 15616.
1326 conjugacy classes of subgroups.
The subgroup lattice has 586 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×#16840637 | C2 | semidirect |
| 253. C22×C61 | #341 | semidirect |
| 269. C2×D61 | #341 | semidirect |
| 322. C61 | #10734 | semidirect |
| 563. C22 | #16840637 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
