Order 15616.
754 conjugacy classes of subgroups.
The subgroup lattice has 266 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #21446589 | C2 | semidirect |
| 3. #21446583 | C2 | semidirect |
| 22. C61×#424 | C4 | semidirect |
| 146. #424 | Dic61 | semidirect |
| 156. C61 | #21967 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
