Order 15616.
1422 conjugacy classes of subgroups.
The subgroup lattice has 180 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 12. C61×#376 | C4 | semidirect |
| 99. #376 | Dic61 | semidirect |
| 103. C61 | #13854 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
