Order 15616.
614 conjugacy classes of subgroups.
The subgroup lattice has 264 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #21461458 | C2 | semidirect |
| 3. #21461407 | C2 | semidirect |
| 74. D61⋊C8 | Q16 | semidirect |
| 159. C61 | #17958 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
