Order 15616.
1038 conjugacy classes of subgroups.
The subgroup lattice has 294 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 4. #21461918 | C2 | semidirect |
| 137. Dic61 | #424 | semidirect |
| 171. C61 | #21143 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
