Order 15616.
738 conjugacy classes of subgroups.
The subgroup lattice has 338 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 15. C61×#391 | C4 | semidirect |
| 16. C61×#389 | C4 | semidirect |
| 179. #391 | Dic61 | semidirect |
| 180. #389 | Dic61 | semidirect |
| 189. C61 | #9144 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
