Order 15616.
660 conjugacy classes of subgroups.
The subgroup lattice has 340 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 17. C61×#398 | C4 | semidirect |
| 181. #398 | Dic61 | semidirect |
| 189. C61 | #9027 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
